The 1940-41 Svenska Serien season was the sixth season of the Svenska Serien, the top level ice hockey league in Sweden. Hammarby IF won their third straight league title. In a change of format from previous seasons, the 8 teams all played each other once, after which they split into an upper group and a lower group based on their performance in the first 7 matches. They then played an additional match against each of the other three teams in their half, resulting in a 10-game season.
