The 1972 United States House of Representatives elections were held on November 7, 1972, to elect U.S. representatives to serve in the 93rd United States Congress. This was the first election held after the 1970 United States redistricting cycle. It coincided with the landslide reelection victory of President Richard M. Nixon. Nixon's Republican Party managed to gain a net of twelve House of Representatives seats from the Democratic Party, although the Democrats retained a majority.

This was the first election in which citizens at least 18 years of age (instead of 21 and older) could vote, due to the recent passage of the 26th Amendment. This was the last time until 2022 that a Democrat would win a House seat in Alaska, and the first time since 1888 that a Republican won a House seat in Louisiana.

Special elections Six special elections were also held throughout the year, six before November and one concurrent with the November general election.
