The Johto League (Japanese: ジョウトリーグ Jōto League) is the regional Pokémon League of the Johto region. It consists of a network of eight Gyms and the Elite Four. Less commonly, it is known as the Silver League.

Pokémon Trainers who earn eight Badges from sanctioned Johto League Gyms qualify to fight in Johto League competitions.
