The 1978 United States House of Representatives elections was an election for the United States House of Representatives on November 7, 1978, to elect members to serve in the 96th United States Congress. They occurred in the middle of Democratic President Jimmy Carter's term, amidst an energy crisis and rapid inflation. The Democratic Party lost a net of 15 seats to the Republican Party, and thus lost their two-thirds supermajority, but still maintained a large 277-seat majority.

The 1976 United States House of Representatives elections were elections for the United States House of Representatives on November 2, 1976, to elect members to serve in the 95th United States Congress. They coincided with Jimmy Carter's election as president. Carter's narrow victory over Gerald Ford had limited coattails, and his Democratic Party gained a net of only one seat from the Republican Party in the House. The result was nevertheless disappointing to the Republicans, who were hoping to win back some of the seats they lost in the wake of the Watergate scandal two years earlier.
