The 1970 United States House of Representatives elections was an election for the United States House of Representatives held on November 3, 1970, to elect members to serve in the 92nd United States Congress. They occurred in the middle of Richard M. Nixon's first term as president. His party, the Republican Party, lost a net of 12 seats to the Democratic Party, which thereby increased its majority in the House.

Pursuant to the Uniform Congressional District Act, this was the first House election since the 1930 elections in which all 50 states used a single-member-district system to elect representatives instead of using at-large congressional districts.

401 incumbent members sought reelection, but 10 were defeated in primaries and 12 defeated in the general election for a total of 379 incumbents winning.^[1]
