2022 Ohio House of Representatives election

The 2022 Ohio House of Representatives elections were held on November 8, 2022, to elect representatives in all 99 districts of the Ohio House of Representatives. Members were elected in single-member constituencies to two-year terms. These elections were held concurrently with various federal and state elections, including for Governor of Ohio and the Ohio Senate.

Although primary elections were originally scheduled for May 3, they were postponed to August 2 after the Supreme Court of Ohio rejected state legislative maps approved by the state redistricting commission as part of the 2020 redistricting cycle.
