The 2026 United States Senate election in Louisiana will be held on November 3, 2026, to elect a member of the United States Senate to represent the state of Louisiana. Incumbent Republican senator Bill Cassidy, who was re-elected in 2020, is running for re-election to a third term. Cassidy's vote to convict Donald Trump in his second impeachment trial has led to primary challenges against him.

Following the enactment of House Bill 17 in 2024, this will be the first U.S. Senate election in Louisiana to utilize party primaries instead of a single blanket primary since 2010.
