GameStorm is a fan-run not-for-profit annual gaming convention held in the spring in the Portland, Oregon metro area.
GameStorm started in 1998 as a fan-run event at the Clackamas, Oregon Denney's Convention Center.
GameStorm also hosts panel discussions about games and gaming-related topics, provides space for designers to play-test new products, and cross-promotes for other area conventions.
GameStorm provides a number of different activities for gaming fandom: GameStorm, like OryCon, is run entirely by fans, with no paid staff, and is sponsored by Oregon Science Fiction Conventions, Inc. (OSFCI), a 501(c)3 not-for-profit corporation.
GameStorm 25 will be March 20-23, 2025 at the DoubleTree by Hilton Hotel Portland, Lloyd Center.
