Pokémon Stadium 2 is a strategy video game developed by Nintendo EAD and published by Nintendo for the Nintendo 64. It features all 251 Pokémon from the first and second generations of the franchise. It was released in North America on March 26, 2001. In Western regions it was titled Pokémon Stadium 2, as it was the second Stadium game to be released outside Japan, in which it was the third game in the series. It supports Dolby Surround sound.

Pokémon Stadium 2 does not have a storyline. Progress can be made by winning trophies in the Stadium, a tournament mode consisting of four "Cups", as well as completing the Gym Leader Castle, where the player earns badges by defeating Gyms specializing in different Pokémon types. When all Stadium trophies have been won and the Gym Leader Castle is completed, the player's rival will want to battle. Defeating the rival will unlock Round 2, in which the player must re-challenge the Stadium, Gym Leader Castle, and the Rival at a higher difficulty level.
