iO Featured Shows and Harold Teams

The iO Theater has been -and continues to be- the home for some of the most popular comedic shows in Chicago for over two decades.

Shows like TJ & Dave, The Armando Diaz Experience, The Improvised Shakespeare Company, The Deltones, and more, have helped make The iO Theater the premier venue for long-form improvisation.
