The 2022 Alaska Senate elections took place on November 8, 2022, with the primary elections being held on August 16, 2022. State senators serve four-year terms in the Alaska Senate, with half of the seats normally up for election every two years. However, because most districts were greatly changed in redistricting, elections were held for 19 of the 20 seats; the only exception is District T, represented by Democrat Donny Olson, which was mostly unchanged in redistricting and thus did not have an election. Some senators were elected to serve four-year terms, while others would serve shortened two-year terms.
