The House of Representatives of the Philippines (Filipino: Kapulungan ng mga Kinatawan ng Pilipinas, Kamara or Camara de Representantes from the Spanish word cámara, meaning "chamber") is the lower house of Congress, the bicameral legislature of the Philippines, with the Senate of the Philippines as the upper house. The lower house is usually called Congress,^{[lower-alpha 3]} although the term collectively refers to both houses.^[1]

Members of the House are officially styled as representative (Filipino: kinatawan) and sometimes informally called congressmen or congresswomen (Filipino: mga kongresista) and are elected to a three-year term. They can be re-elected, but cannot serve more than three consecutive terms except with an interruption of one term like the senate. Around eighty percent of congressmen are district representatives, representing a particular geographical area. The 19th Congress has 253^[2] congressional districts. Party-list representatives are elected through the party-list system which constitutes not more than twenty percent of the total number of representatives.

Aside from needing its agreement to every bill in order to be sent for the president's signature to become law, the House of Representatives has power to impeach certain officials and all franchise and money bills must originate from the lower house.

The House of Representatives is headed by the speaker (Filipino: Ispiker). The position is currently held by Rep. Martin Romualdez. The speaker of the House is the third in the presidential line of succession, after the vice and senate presidents. The official headquarters of the House of Representatives is at the Batasang Pambansa (literally "national legislature") located in Batasan Hills, Quezon City. The building is often simply called Batasan and the word has also become a metonym to refer to the House of Representatives.

The Philippines uses parallel voting for its lower house elections. For the 2022 elections, there will be 316 seats in the House; 253 of these are district representatives, and 63 are party-list representatives. The number of seats to be disputed may change depending on the creation of new congressional districts.

Philippine law mandates that there should be one party-list representative for every four district representatives. District representatives are elected under the plurality voting system from single-member districts. Party-list representatives are elected via the nationwide vote with a 2% election threshold, with a party winning not more than three seats. The party with the most votes usually wins three seats, then the other parties with more than 2% of the vote two seats. At this point, if all of the party-list seats are not filled up, the parties with less than 2% of the vote will win one seat each until all party-list seats are filled up.

Political parties competing in the party-list election are barred from participating district elections, and vice versa, unless permitted by the Commission on Elections. Party-lists and political parties participating in the district elections may forge coalition deals with one another.

Campaigning for elections from congressional districts seats are decidedly local; the candidates are most likely a part of an election slate that includes candidates for other positions in the locality, and slates may comprise different parties. The political parties contesting the election make no attempt to create a national campaign.

Party-list campaigning, on the other hand, is done on a national scale. Parties usually attempt to appeal to a specific demographic. Polling is usually conducted for the party-list election, while pollsters may release polls on specific district races. In district elections, pollsters do not attempt to make forecasts on how many votes a party would achieve, nor the number of seats a party would win; they do attempt to do that in party-list elections, though.

The members of the House of Representatives who are also its officers are also ex officio members of all of the committees and have a vote.

The leadership positions, except for the Secretary General and Sergeant-at-Arms, are currently vacant. The terms of office of the officers elected during the 18th Congress ended on June 30, 2022. On July 25, 2022, the 19th Congress of the Philippines shall elect among themselves their leaders.

The qualifications for membership in the House are expressly stated in Section 6, Art. VI of the 1987 Philippine Constitution as follows:

• No person shall be a Representative unless he/she is a natural-born citizen of the Philippines, and on the day of the election, is at least 25 years of age, able to read and write, a registered voter except for a party-list representative, and a resident of the country for not less than one year immediately preceding the day of the election.
• The age is fixed at 25 and must be possessed on the day of the elections, that is, when the polls are opened and the votes cast, and not on the day of the proclamation of the winners by the board of canvassers.
• With regard to the residence requirements, it was ruled in the case of Lim v. Pelaez that it must be the place where one habitually resides and to which he, after absence, has the intention of returning.
• The enumeration laid down by the 1987 Constitution is exclusive under the Latin principle of expressio unius est exclusio alterius. This means that Congress cannot anymore add additional qualifications other than those provided by the Constitution.

There are two types of congressmen: those who represent geographic districts, and those who represent party-lists. The first-past-the-post (simple plurality voting) method is used to determine who represents each of the 243 geographic districts. The party-list representatives are elected via the party-list system. The party-list representatives should always comprise 20% of the seats.

Originally set at 200 in the ordinance of the 1987 constitution, the number of districts has grown to 243. All of the new districts are via created via piecemeal redistricting of the then existing 200 districts, and via the creation of new provinces and cities. The constitution gave Congress to nationally redistrict the country after the release of every census, but this has not been done.

The original 200 districts meant that there should have been 50 party-list representatives. However, the constitution did not give the specifics on how party-list congressmen should have been elected. This led to presidents appointing sectoral representatives, which were then approved by the Commission on Appointments; only a handful of sectoral representatives were seated in this way. With the enactment of the Party-List System Act, the first party-list election was in 1998; with the 2% election threshold, a 3-seat cap and tens of parties participating, this led to only about a fraction of the party-list seats being distributed. Eventually, there had been several Supreme Court decisions changing the way the winning seats are distributed, ensuring that all party-list seats are filled up.

There were supposed to be 245 congressional districts that were to be disputed in the 2019 election, so there were 61 party-list seats contested in the party-list election. Elections in two of these districts were delayed due to its creation right before campaigning. The Supreme Court ruled that one district be contested in the next (2022) election, then the Commission on Elections applied the court's ruling to the other district, bringing the number of districts to 243, while still keeping the 61 party-list representatives, for a total of 304 seats.

Vacancies from representatives elected via districts are dealt with special elections, which may be done if the vacancy occurred less than a year before the next regularly-scheduled election. Special elections are infrequently done; despite several vacancies, the last special election was in 2023. For party-list representatives, the nominee next on the list is asked to replace the outgoing representative; if the nominee agrees, then that person would be sworn in as a member, if the nominee doesn't agree, then the nominee after that person is asked, and the process is repeated. Vacating party-list representatives have always been replaced this way.

Congress is mandated to reapportion the legislative districts within three years following the return of every census.^[10] Since its restoration in 1987, Congress has not passed any general apportionment law, despite the publication of six censuses in 1990, 1995, 2000, 2007, 2010 and 2015.^[11] The increase in the number of representative districts since 1987 were mostly due to the creation of new provinces, cities, and piecemeal redistricting of certain provinces and cities.

The apportionment of congressional districts is not dependent upon a specially-mandated independent government body, but rather through Republic Acts which are drafted by members of Congress. Therefore, apportionment often can be influenced by political motivations. Incumbent representatives who are not permitted by law to serve after three consecutive terms sometimes resort to dividing their district, or even creating a new province which will be guaranteed a seat, just so that their allies be able to run, while "switching offices" with them. Likewise, politicians whose political fortunes are likely to be jeopardized by any change in district boundaries may delay or even ignore the need for reapportionment.

Since 1987, the creation of some new congressional districts have been met with controversy, especially due to incumbent political clans and their allies benefiting from the new district arrangements. Some of these new congressional districts are tied to the creation of a new province, because such an act necessarily entails the creation of a new congressional district.

• Creation of Davao Occidental, 2013: The rival Cagas and Bautista clans dominate politics in the province of Davao del Sur; their members have been elected as congressional representatives for the first and second districts of the province since 1987. However, the province's governorship has been in contest between the two clans in recent years: Claude Bautista, the current governor, was elected in 2013; before that Douglas Cagas served as governor from 2007 to 2013, after succeeding Benjamin Bautista Jr. who served from 2002 to 2007.^[12] Supporters of both clans have been subjected to political violence, prompting the police to put the province of Davao del Sur in the election watchlist.^[13] The law which created Davao Occidental, Republic Act No. 10360, was co-authored by House Representatives Marc Douglas Cagas IV and Franklin Bautista as House Bill 4451; the creation of the new province is seen as a way to halt the "often violent" political rivalry between the clans by ensuring that the Cagas and Bautista clans have separate domains.^[13]
• Reapportionment of Camarines Sur, 2009: A new congressional district was created within Camarines Sur under Republic Act No. 9716, which resulted in the reduction of the population of the province's first district to below the Constitutional ideal of 250,000 inhabitants. The move was seen as a form of political accommodation that would (and ultimately did) prevent two allies of then-President Gloria Macapagal Arroyo from running in the same district. Rolando Andaya, who was on his third term as congressman for the first district, was appointed Budget Secretary in 2006; his plans to run as representative of the same district in 2010 put him in direct competition with Diosdado Macapagal-Arroyo, the president's youngest son, who was also seeking re-election. Then-Senator Noynoy Aquino challenged the constitutionality of the law but the Supreme Court of the Philippines ultimately ruled that the creation of the new district was constitutional.^[14]
• Creation of Dinagat Islands, 2007: The separation of Dinagat Islands from Surigao del Norte has further solidified the hold of the Ecleo clan over the impoverished and typhoon-prone area, which remains among the poorest provinces in the country.^[15]

The House of Representatives is modeled after the United States House of Representatives; the two chambers of Congress have roughly equal powers, and every bill or resolution that has to go through both houses needs the consent of both chambers before being passed for the president's signature. Once a bill is defeated in the House of Representatives, it is lost. Once a bill is approved by the House of Representatives on third reading, the bill is passed to the Senate, unless an identical bill has also been passed by the lower house. When a counterpart bill in the Senate is different from the one passed by the House of Representatives, either a bicameral conference committee is created consisting of members from both chambers of Congress to reconcile the differences, or either chamber may instead approve the other chamber's version.

Just like most lower houses, franchise and money bills originate in the House of Representatives, but the Senate may still propose or concur with amendments, same with bills of local application and private bills. The House of Representatives has the sole power to initiate impeachment proceedings, and may impeach an official by a vote of one-third of its members. Once an official is impeached, the Senate tries that official.

The Batasang Pambansa Complex (National Legislature) at Quezon City is the seat of the House of Representatives since its restoration in 1987; it took its name from the Batasang Pambansa, the national parliament which convened there from 1978 to 1986.

The Philippine Legislature was inaugurated at the Manila Grand Opera House at 1907, then it conducted business at the Ayuntamiento in Intramuros. Governor-General Leonard Wood summoned the 2nd Philippine Legislature at Baguio and convened at The Mansion in Baguio for three weeks. The legislature returned to the Ayutamiento, as the Legislative Building was being constructed; it first convened there on July 26, 1926. The House of Representatives continued to occupy the second floor until 1945 when the area was shelled during the Battle of Manila. The building was damaged beyond repair and Congress convened at the Old Japanese Schoolhouse at Lepanto^[18] (modern-day S. H. Loyola) Street, Manila until the Legislative Building can be occupied again in 1949. Congress stayed at the Legislative Building, by now called the Congress Building, until President Marcos shut Congress and ruled by decree starting in 1972.^[19]

Marcos then oversaw the construction of the new home of parliament at Quezon City, which convened in 1978. The parliament, called the Batasang Pambansa continued to sit there until the passage of the 1986 Freedom Constitution. The House of Representatives inherited the Batasang Pambansa Complex in 1987.

The members of the House of Representatives, aside from being grouped into political parties, are also grouped into the "majority bloc", "minority bloc" and "independents" (different from the independent in the sense that they are not affiliated into a political party). Originally, members who voted for the winning Speaker belong to the majority and members who voted for the opponent are the minority. The majority and minority bloc are to elect amongst themselves a floor leader. While members are allowed to switch blocs, they must do so in writing. Also, the bloc where they intend to transfer shall accept their application through writing. When the bloc the member ought to transfer refuses to accept the transferring member, or a member does not want to be a member of either bloc, that member becomes an independent member. A member that transfers to a new bloc forfeits one's committee chairmanships and memberships, until the bloc the member transfers to elects the member to committees.

The membership in each committee should be in proportion to the size of each bloc, with each bloc deciding who amongst them who will go to each committee, upon a motion by the floor leader concerned to the House of Representatives in plenary. The Speaker, Deputy Speakers, floor leaders, deputy floor leaders and the chairperson of the Committee on Accounts can vote in committees; the committee chairperson can only vote to break a tie.

To ensure that the representatives each get their pork barrel, most of them will join the majority bloc, or even to the president's party, as basis of patronage politics (known as the Padrino System locally); thus, the House of Representatives always aligns itself with the party of the sitting president.

The majority bloc sits at the right side of the speaker, facing the House of Representatives.
