WJR (760 AM) is a commercial radio station in Detroit, Michigan, owned by Cumulus Media, with a news/talk radio format. Most of WJR's broadcast studios, along with its newsroom and offices, are in the Fisher Building in Detroit's New Center area. A tower atop the Fisher Building relays WJR's audio to the transmitter site, and at one time WJR-FM (currently WDVD) also used this tower. There is an additional satellite studio in the Wintergarden of the GM Renaissance Center in downtown Detroit.

WJR is a Class A clear channel station, operating with 50,000 watts, the maximum power for AM stations in the United States, around the clock. WJR's 1934 transmitter building — which has been called "one of the best Art Deco transmitter buildings ever"[2] — and transmitter tower are located near (and visible from) the intersection of Sibley and Grange Roads in Riverview, Michigan.[3]

Due to WJR's low transmitting frequency and high power, omnidirectional signal, plus the region's mostly flat land and good ground conductivity,[4] the station has unusually large daytime coverage, equivalent to that of a full-power FM station. Its daytime signal provides at least secondary coverage to most of the southern Lower Peninsula, as well as almost half of Ohio (with Cleveland and Toledo getting city-grade coverage) and slivers of Indiana and Pennsylvania. At night it can be heard throughout much of eastern North America with a good radio.

WJR programming is streamed via the web, and is simulcast on WDVD's 96.3 FM HD2 subchannel.[5] WJR is also licensed to broadcast a digital hybrid (HD) signal.[6]

WJR is Michigan's primary entry point station for the Emergency Alert System.
