Black Building, Art Moderne office building in downtown Fargo, United States

The Black Building at 114-118 Broadway is an eight-story Art Moderne building, the tallest in Fargo's downtown historic district. Its Indiana limestone facade sets it apart from the surrounding brick. It was designed by Lang, Raugland, and Lewis of Minneapolis with Fargo consulting architects Ole A. Braseth and S. Marius Houkom.

Norman B. Black, publisher of the Fargo Forum, erected the Black Building at 114-118 Broadway and named it for himself. It was designed by Lang, Raugland and Lewis of Minneapolis with Fargo architects Ole A. Braseth and S. Marius Houkom. In 2016 it was individually listed on the National Register of Historic Places for its architecture and its association with Black.

The building once housed WDAY radio station, and the station's announcers mentioned the Black Building in every broadcast as part of the station identification. This made the building a familiar landmark in the ears of local listeners throughout the region.

The building stands at 114-118 Broadway in the Downtown Fargo District, within the historic district listed on the National Register. It was purchased in 2015, and a municipal bond issue connected to the building failed. Visitors can view the Indiana limestone facade from the street; the sources give no information on interior access.

The Black Building was individually listed on the National Register of Historic Places in 2016, a step its owners took to recognize both its architecture and its link to George Mumford Black. Black, a newspaper publisher who bought the Fargo Forum in 1917, is credited with creating the one-cent sale.
