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

Louisiana stayed at eight house seats following the 1970 census, but the Eighth District's boundaries were radically altered. New governor Edwin W. Edwards ordered the district to take in territory far to the south and east of its traditional base of Alexandria, which included many African-American and progressive white voters. The change was largely regarded as an election deal between Edwards and former Rep. Gillis Long, who finished third in the Democratic Primary in the 1971 Louisiana Governor's Election behind Edwards and J. Bennett Johnston. Long easily won back the Eighth District seat he lost in 1964 to cousin Speedy Long. Speedy Long retired when his home of LaSalle Parish was shifted to the Fifth District, where incumbent Otto Passman was entrenched.

The non-voting delegate to the House of Representatives from the District of Columbia is elected for two-year terms, as are all other Representatives and Delegates minus the Resident Commissioner of Puerto Rico, who is elected to a four-year term.
The election for the Delegate from the District of Columbia featured winner Walter E. Fauntroy (D), who won his first re-election after winning the special election in the previous year.
Walter E. Fauntroy, a Democrat, sought re-election for his second term to the United States House of Representatives. Fauntroy was opposed in this election by Republican challenger William Chin-Lee who received 25.12%, and Statehood Party candidate Charles I. Cassell who received 11.92%. This resulted in Fauntroy being elected with 60.64% of the vote.
Democrat Ron de Lugo was elected as the first delegate from United States Virgin Islands's at-large congressional district defeating Republican Victor Scheider.
