The Rozzie Square Theater is primarily an improv-centric comedy venue, founded and built in May 2018. The theater's mission is to build communities and unite people through laughter while making improv accessible and useful.

The Rozzie Square Theater offers a variety of shows known globally and locally - from ComedySportz (in 30 cities in the U.S. and England) and The Boston Magic Lab, to local staples like Riot Improv and SUZZY sketch comedy. Additional programming found at The Rozzie Square Theater includes storytelling, neofuturist theater, and stand-up shows.

The theater's most popular offering is The Free Drop-In, a free drop-in workshop that introduces improv and gives new and potential students a chance to learn more about improv and the coaches at the theater.

The theater is the only brick-and-mortar comedy club in Boston owned by a Woman and Asian American.
