The Chicago Theatre, originally known as the Balaban and Katz Chicago Theatre, is a landmark theater located on North State Street in the Loop area of Chicago, Illinois. Built in 1921, the Chicago Theatre was the flagship for the Balaban and Katz (B&K) group of theaters run by A. J. Balaban, his brother Barney Balaban and partner Sam Katz. Along with the other B&K theaters, from 1925 to 1945 the Chicago Theatre was a dominant movie theater enterprise. Currently, Madison Square Garden, Inc. owns and operates the Chicago Theatre as a 3600 seat performing arts venue for stage plays, magic shows, comedy, speeches, sporting events and popular music concerts.

The Loop, one of Chicago's 77 designated community areas, is the central business district of the city and is the main section of Downtown Chicago. Home to Chicago's commercial core, it is the second largest commercial business district in North America after Midtown Manhattan in New York City, and contains the headquarters and regional offices of several global and national businesses, retail establishments, restaurants, hotels, and theaters, as well as many of Chicago's most famous attractions. It is home to Chicago's City Hall, the seat of Cook County, and numerous offices of other levels of government and consulates of foreign nations. The intersection of State Street and Madison Street is the origin point for the address system on Chicago's street grid. Most of Grant Park's 319 acres are in the eastern section of the community area. The Loop community area is bounded on the north and west by the Chicago River, on the east by Lake Michigan, and on the south by Roosevelt Road.
