23 seats are elected by party-list proportional representation with a 5% electoral threshold, with the other half elected in 23 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.

The following parties were relieved from the necessity to collect signatures:[2] New People will take part in Kemerovo Oblast legislative election for the first time, while Patriots of Russia, who entered the legislature after the 2018 elections, had been dissolved prior (and its former regional leader Yury Skvortsov heading A Just Russia – For Truth list in the current election).

23 single-mandate constituencies were formed in Kemerovo Oblast.

Aleksey Zelenin (United Russia) was re-elected as Chairman of the Legislative Assembly,[4] while Kemerovo city official Nadezhda Ilyina (United Russia) was appointed to the Federation Council, replacing incumbent Senator Dmitry Kuzmin (United Russia).
