Ally Detroit Center (Formerly One Detroit Center) is a skyscraper and class-A office building located downtown which overlooks the Detroit Financial District. Rising 619 feet (189 m), the 43-story tower is the tallest office building in Michigan, and the second tallest building overall in the state behind the central hotel tower of the Renaissance Center, located a few blocks away. Although the Penobscot Building has more floors (45 above-ground floors compared to 43), Ally Detroit Center's floors are taller, with its roof sitting roughly 60 feet (18 m) taller than Penobscot's. Its floor area is 1,674,708 sq ft (155,585.5 m2).

The building was designed by noted architects John Burgee & Philip Johnson, partners influential in postmodern architecture. Ally Detroit Center was constructed from 1991 to 1993. It houses numerous tenants, including many prominent Detroit law firms and PricewaterhouseCoopers. In addition to retail, the building also contains a restaurant and a gym.

The building is famous for its postmodern architectural design topped with Flemish-inspired neo-gothic spires which blend architecturally with the city's historic skyline. It is constructed mainly of granite. Sometimes called a "twin gothic structure", for its pairs of spires, it is oriented North-South and East-West (as named on a plaque along the Windsor waterfront park). Ally Detroit Center won an Award of Excellence for its design in 1996. Ally Detroit Center replicas have become a souvenir item along with those of other Detroit skyscrapers.
