2023 Rostov Oblast Legislative Assembly election

Under current election laws, the Legislative Assembly is elected for a term of five years, with parallel voting. 20 seats are elected by party-list proportional representation with a 5% electoral threshold, with the other half elected in 40 single-member constituencies by first-past-the-post voting. Until 2023 the number of mandates allocated in proportional and majoritarian parts were standing at 30 each. 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.^[1]

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

The following parties were relieved from the necessity to collect signatures:^[2]

• United Russia
• Communist Party of the Russian Federation
• A Just Russia — Patriots — For Truth
• Liberal Democratic Party of Russia
• New People
• Communists of Russia

New People will take part in Rostov Oblast legislative election for the first time, while Party of Pensioners of Russia and People's Alliance, who took part in the last legislative election, had been dissolved prior.

40 single-mandate constituencies were formed in Rostov Oblast, an increase of 10 seats since last redistricting in 2018. To register candidates in single-mandate constituencies need to collect 3% of signatures of registered voters in the constituency.
