WOL (1450 kHz) is an urban talk AM radio station in Washington, D.C. This is the flagship radio station of Radio One. It is co-owned with WDCJ, WKYS, WMMJ, WPRS-FM, and WYCB and has studios located in Silver Spring, Maryland. The transmitter site is in Fort Totten within DC and sharing with WYCB on 1340kHz.

A Baltimore version of this station, WOLB, was created in the early 1990s and shares some of the same programming as WOL.

The station was granted a construction permit, as WWDC, by the Federal Communications Commission (FCC) on October 29, 1940, for a new station to broadcast with 250 watts on 1420 kHz. In March 1941, most stations assigned to this frequency, including WWDC, were reassigned to 1450 kHz, under the provisions of the North American Regional Broadcasting Agreement.

WWDC made its debut broadcast at 8 p.m. on May 3, 1941, airing programming from 8 a.m. to 1 a.m. Studios were at 1000 Connecticut Avenue. An independent station with no network affiliation, the station advertised it would broadcast Associated Press newscasts five minutes before every hour, and "through NBC transcriptions, Station WWDC will present a wide choice of big names in orchestras and radio entertainers from the NBC roster of stars".

On January 26, 1950, the FCC approved the sale of WWDC by Capital Broadcasting, which had just bought WOL (1260 AM) from Cowles Broadcasting, to Peoples Broadcasting Corporation, an affiliate of the local People's Drug Stores, and announced the two stations would be swapping call letters. The change took place February 20, 1950. This swap moved the WOL call letters to 1450 AM.

In 1965, the Sonderling Broadcasting Corporation bought WOL and changed the format from easy listening to rhythm and blues. That year, WOL also became the first rhythm and blues station in Washington to have public affairs programming. "No other medium in the city had WOL's influence and credibility among black Washingtonians from 1965 to about 1975...With finger-popping, hand-clapping and foot-stomping, they were the broadcasters of gospel-influenced, inner city culture," The Washington Post observed. WOL helped popularize "Chocolate City" as a nickname for Washington, according to the Post.

Originally simulcast on its FM sister station WMOD for more extensive coverage, they later changed the FM station to an oldies format. The station slowly deemphasized its music programming and evolved into an African-American based talk station.

For many years the pair was owned by Sonderling Broadcasting, who later sold its assets to Viacom Broadcasting. (After Viacom took over, WMOD-FM became country station WMZQ-FM)
