The 2018 United States House of Representatives elections in Texas were held on Tuesday, November 6, 2018. Voters elected 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 had won in the state since 2006. Democrats won almost 47% of the vote, likely due to the down-ballot effect of Representative Beto O'Rourke's Senate candidacy, in which he won 48.3% of the vote, but also because four Democratic incumbents faced no Republican opposition in their general elections.
Turnout was also more than doubled from the last midterm election.

Because Texas's 22nd congressional district is one of the most diverse in Texas, the Kulkarni campaign took the unorthodox approach of reaching out to infrequent voters in their own neighborhoods and languages, including Gujarati, Marathi, Tamil and Mandarin. If elected, Kulkarni would have become the first Asian-American ever to serve in the Texas congressional delegation.
