Florida's 5th congressional district is a congressional district in the U.S. state of Florida. It includes the southeastern area of Jacksonville which comprises areas such as Arlington, East Arlington, Southside, Mandarin, San Jose, and the Beaches. It stretches south to St. Augustine in St. Johns County.

From 2002 to 2013 the district comprised all of Citrus, Hernando, and Sumter counties and most of Lake, Levy, and Pasco counties and portions of Marion and Polk counties. The district included northern exurbs of Tampa and western exurbs of Orlando within the high-growth Interstate 4 Corridor. This iteration of the 5th district is now largely contained in the 11th district.

As defined by the state legislature in 2013 (which lasted until 2017), the 5th district ran from Jacksonville to Orlando; it was considered one of the most-gerrymandered congressional districts in the country.^[5] Before 2013, similar territory was included in the 3rd district.

After court-mandated redistricting, the district became a majority-minority district from 2017 to 2023. It extended along Florida's northern boundary from Jacksonville to Tallahassee and included all of Baker, Gadsden, Hamilton and Madison counties and portions of Columbia, Duval, Jefferson, and Leon counties.

The district is currently represented by Republican John Rutherford.

Florida's 3rd congressional district was renumbered to 5th congressional district but was little changed in the redistricting process in 2012, still winding from Orlando in the south to central Jacksonville in the north.^[6]

From 1973 to 1993 the erstwhile 3rd district was based in Orange County, including Walt Disney World and most of Orlando. The peculiar shape of the 3rd (now 5th) congressional district dates from reapportionment done by the Florida Legislature after the 1990 U.S. census. The 1993–2012 3rd congressional district was geographically distinctive. Starting from the southern part of the district, it included the Pine Hills area of the Orlando-Kissimmee Metropolitan Area with small pockets of African-American neighborhoods in the cities of Sanford, Gainesville, Palatka, and finally the larger African American communities of Jacksonville.^[7] Connecting these areas were regions which are sparsely populated—either expansive rural areas or narrow strips which are only a few miles wide.^[8][9] Barack Obama received 73% of the vote in this district in the 2008 Presidential election.
