1964 United States House of Representatives elections

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 PresidentLyndon 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 for the first time since 1936. 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.

Disappointment over the results caused House Republicans to replace Minority LeaderCharles Halleck with future President Gerald R. Ford.
