WDCH-FM (99.1 MHz) – branded Bloomberg 99.1 – is a commercial business news radio station licensed to Bowie, Maryland, and serving the Baltimore-Washington metropolitan area. Owned by Audacy, Inc., the station is operated by Bloomberg L.P. as the market network affiliate for Bloomberg Radio. WDCH-FM sometimes airs D.C. United soccer and Washington Wizards basketball games whenever sports radio sister station WJFK-FM (106.7 "The Fan") is carrying a different game.

The studios and offices are near the Washington Navy Yard along the Anacostia River in Southeast Washington, while the station transmitter is in Odenton, Maryland. WDCH is one of the few stations that targets both Baltimore and Washington DC, since its transmitter is located halfway between the two cities, providing a strong city-grade signal to both. WDCH-FM programming is also heard on the HD-2 digital subchannel on 105.7 WJZ-FM.
