Since 1963, the Improvisation Comedy Clubs have remained the premier stages for live comedy in the United States. Over the decades, the talent who have graced Improv stages represent the Who’s Who in American comedy. Ontario Improv opened in 2001. Located in the Southern California region known as the Inland Empire, Ontario Improv is situated in the thriving Ontario Mills shopping center and offers a combination of A-list comedy, good food and cocktails. The venue is conveniently close to highways 10 and 15, just five miles away from the Ontario International airport. There is a surplus of lodging within minutes of the location. Ontario Improv retains a true club vibe with amphitheater-style seating, allowing guests to feel close to the show from every seat in the house. There is plenty of free self-parking available, plus valet parking on weekends. At Ontario Improv, comedians such as Paul Mooney and Richard Jeni have graced the stage. The Wayans Bros, Corey Holcomb, Felipe Esparza and Gary Owen are frequent headliners. The venue books comedians up to six nights each week, alternating between big-name headliners and up-and-comers. At Ontario Improv, there is something for everyone.
