The 1964 United States House of Representatives elections was an election for the United States House of Representatives on November 3, 1964, to elect members to serve in the 89th United States Congress. They coincided with the election to a full term of President Lyndon B. Johnson. Johnson's landslide victory over Barry Goldwater allowed his Democratic Party to gain a net of 36 seats from the Republican Party, giving them a two-thirds majority in the House. The election also marked the first time since Reconstruction that Republicans made inroads in the Deep South, with Republicans winning seats in Georgia for the first time since 1874, and Alabama and Mississippi since 1876.

The 1962 United States House of Representatives elections was an election for the United States House of Representatives on November 6, 1962, to elect members to serve in the 88th United States Congress. They occurred in the middle of President John F. Kennedy's term. As in most midterm elections, Kennedy's Democratic Party lost seats to the opposition Republican Party, but retained a majority. House Democrats were expected to lose their majority, but the resolution over the Cuban Missile Crisis just a few weeks prior led to a rebound in approval for the Democrats under President Kennedy.
