2020 Japanese Regional Leagues

The 2020 Japanese Regional Leagues (Japanese: 2020 地域リーグ, Hepburn: 2020 Chiiki Rīgu) was the 55th edition of the Japanese Regional Leagues, the fifth tier of the Japanese association football league system. A total of 120 teams competed, split into 9 groups, in the Japanese Regional Leagues. Due to the COVID-19 pandemic in Japan, all matches in some of the regions were changed from double round-robin into single round-robin, except Chūgoku and Tōkai which used a cup style knockout competition.

All regional champions qualified for the 2020 Regional Champions League. Like the J.League, there was no relegation in this season to Prefectural Leagues (promotion and relegation between divisions were still available for some regions).
