333 North Michigan is an Art Deco skyscraper located in the Loop community area of Chicago, Illinois. It was constructed in 1927 on the site of Fort Dearbon. Architecturally, it is noted for its dramatic upper-level setbacks that were inspired by the 1923 skyscraper zoning laws. Geographically, it is known as one of the four 1920s flanks of the Michigan Avenue Bridge (along with the Wrigley Building, Tribune Tower and the London Guarantee Building) that are contributing properties to the Michigan–Wacker Historic District, which is a U.S. Registered Historic District.
It was designated a Chicago Landmark on February 7, 1997. The building is embellished by a polished marble base, ornamental bands, and reliefs depicting frontiersmen and Native Americans at Fort Dearborn, which partially occupied the site.
