The Joan W. and Irving B. Harris Theater for Music and Dance is a 1,499-seat theater for the performing arts located along the northern edge of Millennium Park on Randolph Street in the Loop community area of Chicago in Cook County, Illinois, US. The theater, which is largely underground due to Grant Park-related height restrictions, was named for its primary benefactors, Joan and Irving Harris. It serves as the park's indoor performing venue, a complement to Jay Pritzker Pavilion, which hosts the park's outdoor performances.

Millennium Park is a public park located in the Loop community area of Chicago, operated by the Chicago Department of Cultural Affairs.

Featuring a variety of public art, outdoor spaces and venues, the park is bounded by Michigan Avenue, Randolph Street, Columbus Drive and East Monroe Drive. In 2017, Millennium Park was the top tourist destination in Chicago and in the Midwest, and placed among the top ten in the United States with 25 million annual visitors.
