The Joan W. and Irving B. Harris Theater for Music and Dance (also known as the Harris Theater for Music and Dance, the Harris & Harris Theater or, most commonly, the Harris Theater) is a 1,525-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.
