Retrogathering is a Swedish event for collectors, players, and enthusiasts of vintage computers and video games, with a focus on technology and gaming from around 1970 to 2000. The event brings the retro-gaming community together for exhibitions, competitions, talks, and opportunities to meet fellow enthusiasts. It has been held at venues including Alviks Medborgarhus in Stockholm and Växhuset in Västerås, and its history dates back to 2006.

Programming has featured themed displays on classic systems and games, guest speakers, arcade games, tournaments, and auctions. Past themes have included the Atari 2600, Game Boy, MSX, and early Nintendo and Capcom releases. A recurring highlight is the Swedish Pong Championship, known as Pong-SM, which has crowned six different champions across its first 11 editions. Retrogathering also shares event information, photographs, practical guidance for visitors and exhibitors, and updates through its website and social media. After announcing a pause during 2026, the organizers plan to return in 2027 with renewed energy.
