L-13 is a contemporary arts collaborative gallery space founded by Harry Adams, James Cauty, Billy Childish, Jamie Reid, Geraldine Swayne, AS Waghorne and Sexton Ming.

After Aquarium L-13 closed in 2008, the group set up the L-13 Light Industrial Workshop in May 2009. The space not only hosts exhibitions, but functions as an artists' studio, design company, media imprint and creative network.
