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. The GameStorm group often provides gaming programming at OryCon and other conventions in the Pacific Northwest as well, and has an extensive game library. 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 26 will be March 19-22, 2026 at the Holiday Inn Portland - Columbia Riverfront.
