The Rosemont Theatre (formerly the Akoo Theatre at Rosemont) is a concert hall in Rosemont, Illinois, a suburb of Chicago. The venue, which has seats for 4,400 people and opened in 1995, hosts many different musical artists and shows. It is located near O'Hare International Airport, Allstate Arena and Donald E. Stephens Convention Center.

The Mayor of Rosemont, Bradley Stephens, is currently planning to sell the site to the state of Illinois to use as a casino in an effort to gain revenue. The idea was initially pitched in September 2007 and again in May 2008, to lawmakers in Springfield who have expressed interest in the state-owned casino as they are still seeking ways to support a $31 million public works program advanced by former Governor Rod Blagojevich.In 2012, Akoo International, Inc. purchased five-year naming rights for $1.5 million.The company specializes in making interactive media for college dorms, malls and shopping centers. Along with naming rights, the company also create visual content for artists performing at the theatre and the Allstate Arena. Akoo International went out of business in January 2013 and the venue returned to its former name beginning March 2013.
