The 2021–22 Korisliiga season was the 82nd season of the top professional basketball league in Finland.
The twelve teams played two times against each one of the other teams for a total of 22 games. The league splits into two groups (one with the first 6 teams and the other with the last 6 teams) and each team played two games against each one of the teams from the same group (for a total of 10 games). The six teams from the first group and the best two teams from the second group joined the playoffs. The last team would be directly relegated.[1]
Ura Basket did not apply for a serial licence for the Men's Korisliiga for season 2021-2022. Ura Basket will be the Division I B team, where the club's own breeders will be able to represent Kaarina basketball at the national level. In the 2020–2021 season, LoKoKo Bisons was able to celebrate the Men's Division A championship. The Bisons climbed back to the Premier Korisliiga to season 2021-2022.
