The Pokémon 25th anniversary (Japanese: ポケモン 25周年, Hepburn: Pokemon 25 Shūnen), officially branded as Pokémon25, was a celebration held throughout 2021 in commemoration of the twenty-fifth anniversary of the Pokémon franchise, which began with the original Japanese release of Pocket Monsters Red and Green for the Game Boy on February 27, 1996.

The Pokémon Company presented the logo for the anniversary in front of a giant balloon of Pikachu, who has made a regular appearance at the parade since 2001.
