Clockwork Alchemy is the San Francisco Bay Area’s own steampunk convention, celebrating alternative history, sci-fi, and fantasy.

For anyone who loves sci-fi with an alternate history spin, Clockwork Alchemy provides a 3-day event with an immersive environment, welcoming community, and many hours of panels, games, social events, and concerts. Clockwork Alchemy is a great event for readers, artists, makers, crafters, costumers, fans, families and more, coming the weekend of April 7-9, 2023.

This coming year’s theme is “Villains & Heroes” in our new lair the San Mateo Marriot. We look forward to seeing you in 2023!


Immerse yourself in fun and activities all weekend long. Attend educational panels and classes to learn history, science, literature, crafts and martial arts.

In the evenings, the convention transforms into a showcase of entertainment and music, with concerts and dancing.
