WTMJ (620 kHz) is a commercial AM radio station in Milwaukee, Wisconsin. Owned by Good Karma Brands, the station has a news/talk radio format. Its sign-on dates back to 1922 and for most of its history it was owned by The Milwaukee Journal newspaper. On weekdays, it airs news blocks during drive time, local talk shows in middays, sports in the evening and syndicated shows in late nights. It is the flagship station for Milwaukee Brewers baseball and Milwaukee Bucks basketball.

By day, it transmits 50,000 watts, the maximum for AM radio stations in the United States. At night, to avoid interference to other stations, it reduces power to 10,000 watts.[2] In addition, it broadcasts on 250-watt FM translator W277CV at 103.3 MHz.
