BATS Improv (formerly known as "Bay Area Theatresports") is a non-profit improvisational theatre company in San Francisco.
Founded in 1986, their unique style of acting-based improvisational theatre is well known in improv circles around the world.
BATS takes its inspiration from the work of Theatresports creator Keith Johnstone and from San Francisco's own tradition of experimental improvisation.
Since 1986, BATS helped create and define a unique San Francisco style of long-form improvisation—a single-story 2-hour show, complete with intermission—which is distinct from improv seen in much of the rest of the country.
BATS is in residence at the 200-seat Bayfront Theater at historic Fort Mason Center in San Francisco and performs and offers classes year round.
