Sonoma Con is back October 4-5 at the Sonoma County Fairgrounds-and this year, cosplay is joining the fun! More than a traditional comic convention, Sonoma Con celebrates the worlds of trading card games (TCGs), tabletop role-playing games (TTRPGs), video games, Pokémon, cosplay, and all things geeky. Following its successful debut in 2024, organizers are expanding the event with more space, games, tournaments, meetups, cosplay contests, and a new Dungeons & Dragons experience.
