The Grand Circus Park Historic District contains the 5-acre (2.0 ha) Grand Circus Park in Downtown Detroit, Michigan that connects the theatre district with its financial district. It is bisected by Woodward Avenue, four blocks north of Campus Martius Park, and is roughly bounded by Clifford, John R. and Adams Streets. The district was listed on the National Register of Historic Places in 1983. The building at 25 West Elizabeth Street was added to the district in 2000, and additional structures located within the district, but built between 1932 and 1960, were approved for inclusion in 2012.

Downtown Detroit is the central business district and a residential area of the city of Detroit, Michigan, United States. Locally, downtown tends to refer to the 1.4 square mile region bordered by M-10 to the west, Interstate 75 to the north, I-375 to the east, and the Detroit River to the south. Although, it may also refer to the Greater Downtown area, a 7.2 square mile region that includes surrounding neighborhoods such as Midtown, Corktown, Rivertown, and Woodbridge.
