1978 United States House of Representatives elections in Texas

The 1978 United States House of Representatives elections in Texas occurred on November 7, 1978, to elect the members of the state of Texas's delegation to the United States House of Representatives. Texas had twenty-four seats in the House apportioned according to the 1970 United States census.

These elections occurred simultaneously with the United States Senate elections of 1978, the United States House elections in other states, and various state and local elections.

Democrats maintained their majority of U.S. House seats from Texas, but they lost two seats to the Republicans, decreasing their majority to twenty out of twenty-four seats. These elections produced a high level of turnover due to the retirements of several representatives, as well as the electoral defeat of others.
