The 2018 United States House of Representatives elections in Texas were held on Tuesday, November 6, 2018. Voters will elect the 36 U.S. Representatives from the state of Texas, one from each of the state's 36 congressional districts. The elections coincided with the elections of other offices, including the gubernatorial election, as well as other elections to the House of Representatives, elections to the United States Senate and various state and local elections. The primaries were held on March 6 and the run-offs were held on May 22. In 2018, for the first time in at least 25 years, the Texas Democratic Party fielded at least one candidate in each of the state's 36 congressional districts. The state congressional delegation changed from a 25–11 Republican majority to a 23–13 Republican majority, the most seats that Democrats have won in the state since 2006. Democrats won almost 47% of the vote, likely as part of a down-ballot effect of Representative Beto O'Rourke's Senate Candidacy, in which he won 48.3% of the vote.
