The Magnificent Mile, sometimes referred to as The Mag Mile, is an upscale section of Chicago's Michigan Avenue, running from the Chicago River to Oak Street in the Near North Side. The district is located within downtown and one block east of Rush Street. The Magnificent Mile serves as the main thoroughfare between Chicago's Loop business district and its Gold Coast. It is generally the western boundary of the Streeterville neighborhood, to its east, and of River North to the west.

Michigan Avenue is a north-south street in Chicago that runs at 100 east on the Chicago grid. The northern end of the street is at Lake Shore Drive on the shore of Lake Michigan in the Gold Coast Historic District. The street's southern terminus is at Sibley Boulevard in the southern suburb of Dolton, but like many other Chicago streets, it exists in several disjointed segments.
