2022 Hawaii Senate election

The 2022 Hawaii Senate elections were held on November 8, 2022, to elect senators in all 25 districts of the Hawaii Senate. Due to the chamber's use of the 2-4-4 term system, members were elected in single-member constituencies, with half of them serving two-year terms and the other half serving four-year terms. These elections were held concurrently with various federal and state elections, including for governor of Hawaii. Partisan primaries were held on August 13.

The Democratic Party maintained supermajority control of the chamber, although Republicans were able to win two seats, a first for the party since the 2008 election.
