2026 Hawaii Senate election
The 2026 Hawaii Senate election is scheduled to be held on Tuesday, November 3, 2026, to elect 13 of 25 representatives to serve four-year terms in the Hawaii Senate. Partisan primaries will take place on August 8, 2026. Democrats currently hold a veto-proof supermajority in the chamber.
State senators in Hawaii represent an average of 58,405 residents as of the 2020 United States census. If a primary or general election in a district sees only one candidate file, no election will be held. Four general elections in 2024 were canceled due to lack of competition.
