Miracle Mile Historic District, Historic district along North Stone Avenue in Tucson, United States.

Miracle Mile Historic District is an area with 102 properties along North Stone Avenue in Tucson consisting mainly of mid-20th century buildings. Around 215 structures show commercial design and automobile business styles from that era, including motels, diners, and related shops along this street.

The district began in 1937 as a main entry point to Tucson through U.S. Route 80 and 89, before interstate highways were built later. Its role shifted when highway construction redirected traffic and reduced the importance of this original route through town.

The corridor's name comes from a 1930s contest promoting the new northern gateway, and its motels, diners and auto courts served travellers on U.S. Route 80 and 89. Look for the De Luxe Motel (1948), the Flamingo Hotel (1954) and the Riviera Motor Lodge (1953), whose signs and roadside forms mark the strip.

The area sits along North Stone Avenue and is easy to walk through, with good views of the different building styles and facades. Moving slowly helps you see all the architectural details from the street and appreciate the variety of designs throughout the district.

Monterey Court at 505 West Miracle Mile was built in 1952, not 1938, as one of the district's mid-century motor courts. It now operates as a music venue and artist studio, a reuse that keeps a contributing building of the 1920–1963 period in active use.
