The Chicago Theatre, originally known as the Balaban and Katz Chicago Theatre, is a famous theater landmark located on North State Street in the Loop area of Chicago, Illinois. For several decades, it was the city's premier movie theater. Now the Chicago is a leading venue for stage plays, magic shows, comedy, speeches, and popular music concerts.

The structure is seven stories tall and fills nearly one half of a city block. The 60-foot (18 m) wide by six-story tall arch on the State Street façade is designed similarly to the l'Arc de Triomphe in Paris. The coat of arms of the Balaban and Katz chain—two horses holding ribbons of 35 mm film in their mouths outlined by a border of film reels—is set inside a circular Tiffany stained glass window inside the arch. The exterior of the building is covered in off-white terra cotta supplied by the Northwestern Terra Cotta Company with neo-Baroque plaster designs by the McNulty Brothers.

The stage dimensions exceed 60 feet (18 m) in width and 30 feet (9.1 m) in depth. The orchestra pit is approximately 6 feet (1.8 m) below stage level, 54 feet (16 m) wide at the stage lip, with a depth of 15 feet (4.6 m) at center. An adjustable pit filler can be used for performances requiring other levels.
