WBMX (104.1 FM, Mix 104-1) is a radio station with a hot adult contemporary format in Boston, Massachusetts. The format started at 98.5 FM on February 9, 1991, and moved to 104.1 FM, replacing WBCN, on August 12, 2009, to allow for the launch of WBZ-FM at 98.5 the next day. Its studios are located in Brighton, and its transmitter is atop the Prudential Tower.

The call letters WBMX (standing for Black Music EXperience) were originally assigned to 102.7 on the FM dial in Oak Park, Illinois (serving Chicago) from 1973 to 1988. (That station frequency is now home to R&B station WVAZ). The call letters were then assigned to 640 AM in Zeeland, Michigan until 1991, when they were transferred to 98.5 FM in Boston to reflect the station's "Mix" branding.

The WBMX intellectual property originated on the 98.5 FM frequency, which signed on in October 1948 as WNAC-FM under the ownership of the Yankee Network division of General Tire and Rubber, which also owned WNAC (then at 1260 AM, now occupied by WBIX; moved to 680 AM in 1953) and WNAC-TV (channel 7, now occupied by WHDH). The station originally transmitted from WNAC-TV's tower in Medford, using a transmitter originally used for the Yankee Network's FM station on Mount Washington (which was originally considered a Boston station, but was eventually refocused to Portland, Maine), which operated from December 18, 1940, to September 1948 (when it signed off due to increasing costs and a lack of listener interest). As at most FM stations, WNAC-FM initially served as a full-time simulcast of WNAC. The station, along with General Tire's other broadcast holdings, came under the General Teleradio banner in 1952; the division became RKO Teleradio Pictures in 1955 and RKO General in 1959.
