WDIV ("Local 4") is the NBC television station based in Detroit, Michigan, United States. It is the only major television station in the area whose offices and studios are located in the city of Detroit. It is owned by Post-Newsweek Stations and is the flagship station and home base of the group with the offices of the group located alongside WDIV's studios; the "Local" branding now utilized by all stations in the group was launched here alongside its acquiring of flagship status.

The station's signal, transmitted from a 1004-foot (306-meter) antenna located on Greenfield Road in Southfield, encompasses the Metro Detroit area and can be picked up as far away as Flint, Lapeer, Adrian, Toledo, and even London, Ontario.

It also serves several other Canadian cable-TV markets, including Rogers Cable in the city of Ottawa.
