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 vocal opposition to former president Donald Trump has led to speculation that Republicans will field a primary challenge against him.^[1]

Following the enactment of House Bill 17 in 2024, this will be the first U.S. Senate election in Louisiana to utilize closed partisan primaries instead of a single blanket primary since 1974.^[2]
