The 2026 Tyumen Oblast Duma election took place on 18–20 September 2026, on common election day, coinciding with the 2026 Khanty-Mansi Autonomous Okrug legislative election and the 2026 Russian legislative election. All 48 seats in the Oblast Duma were up for re-election. Tyumen Oblast Duma election was held in Tyumen Oblast, Khanty-Mansi Autonomous Okrug and Yamalo-Nenets Autonomous Okrug.

United Russia slightly increased its overwhelming majority in the Oblast Duma, winning 59.6% of the vote and all 24 single-mandate constituencies. Liberal Democratic Party of Russia, Communist Party of the Russian Federation and A Just Russia all lost a single seat each, while New People entered the Oblast Duma for the first time.

Electoral system Under current election laws, the Oblast Duma is elected for a term of five years, with parallel voting. 24 seats are elected by party-list proportional representation with a 5% electoral threshold, with the other half elected in 24 single-member constituencies by first-past-the-post voting. 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. Unlike most regional elections in Russia, party lists in Tyumen Oblast are not divided between territorial groups.

Candidates Party lists To register regional lists of candidates, parties need to collect 0.5% of signatures of all registered voters in Tyumen Oblast.

The following parties were relieved from the necessity to collect signatures: United Russia Communist Party of the Russian Federation Liberal Democratic Party of Russia A Just Russia New People Russian Party of Pensioners for Social Justice Communists of Russia
