Baby of the House is the unofficial title given to the youngest member of a parliamentary house.

In Australia the term is rarely used.

The youngest Baby of the House was Wyatt Roy. He was elected at age 20 in 2010, being the youngest person ever to be elected to an Australian parliament.^[2]

In the Congress of the Philippines, the term "Baby of the House" is rarely used; the term "Benjamin" of the chamber is used instead.^[29] Special treatment is not given to the youngest member of either chamber. However, by tradition, the youngest member of the chamber usually administers the oath of office to their incoming leader (i.e. President of the Senate and Speaker of the House of Representatives).

The minimum age for being a member of the House of Representatives is 25 years old, while for the Senate, it is 35, as stipulated in the 1987 Constitution of the Philippines. In 1933, Benigno Aquino, Sr. became senator at the age of 33;^[30] the Jones Law, which created the Senate, had prescribed the minimum age of 30.

The current Benjamin of the House is Representative Braeden Jaime Cojuangco of the 1st District of Tarlac. Meanwhile, Senator Mark Villar has been the youngest Senator since 2022.^[31]

Becoming the Baby of the House of Commons is regarded as something of an achievement despite the lack of any special treatment that comes with the title. However, some MPs who have held the position for a considerable period – Matthew Taylor was the Baby of the House for over ten years – have found it somewhat embarrassing, as it may suggest that they have a lack of experience, although many holders of the title have gone on to enjoy long and distinguished parliamentary careers.

While the term is used in the Commonwealth Parliaments, Baby of the House or Senate is not in general contemporary use in the United States, nor does being the youngest member confer special treatment in either house of Congress.

Members of the US Congress tend to be older than parliamentarians elsewhere in the English-speaking world, a main factor being that the minimum ages for members of Congress is written into Article One of the United States Constitution, which forbids those under the age of 25 from serving in the House, and those under the age of 30 from serving in the Senate. Moreover, election to the federal Congress is expensive and requires extensive contacts and recognition across a very wide area. Individuals aiming to serve in the federal legislature generally seek election to the state legislature (which generally have lower minimum ages for entry) or other state office before seeking to serve in Washington.

In the 118th Congress, which began on 3 January 2023, the youngest member of the United States House of Representatives is Maxwell Frost, who was born on (1997-01-17) 17 January 1997 (age 27) and was first elected in 2022.
