The 2022 Sakhalin Oblast Duma election took place on 9–11 September 2022, on common election day. All 28 seats in the Oblast Duma were up for reelection.

Electoral system Under current election laws, the Oblast Duma is elected for a term of five years, with parallel voting. 10 seats are elected by party-list proportional representation with a 5% electoral threshold, with the other half elected in 18 single-member constituencies by first-past-the-post voting. Until 2022 the number of mandates allocated in proportional and majoritarian parts were standing at 14 each. Initially, 7 party list mandates and 21 single-member constituencies were proposed, however, this model was declared unconstitutional as it could create a situation, where there would be not enough seats for every qualified party.На Сахалине «нарезали» одномандатные округа под новые выборы Seats in the proportional part are allocated using the Imperiali quota, modified to ensure that every party list, which passes the threshold, receives at least one mandate ("Tyumen method").Закон Сахалинской области от 10 апреля 2008 года N 22-ЗО "О выборах депутатов Сахалинской областной Думы" (с изменениями на 9 июня 2022 года)
