The 2026 United States Senate election in Texas will be held on November 3, 2026, to elect a member of the United States Senate to represent the state of Texas. Incumbent four-term Republican Senator John Cornyn, who was re-elected in 2020 is eligible to run for re-election to a fifth term in office.
Republicans have won every U.S. Senate election in Texas since 1988.
Due to various votes and positions taken by Cornyn on topics such as gun control[1] and immigration,[2] he is considered vulnerable to a primary challenge.
