WMBZ (92.5 MHz "Buzz Country 92.5") is a commercial FM radio station in West Bend, Wisconsin, serving Milwaukee's northern suburbs.

WMBZ and sister station WVTY, which serves Milwaukee's southern suburbs, are co-programmed and air a country music radio format.

WBKV-FM was an easy listening station, playing quarter-hour sweeps of soft instrumentals and mellow vocals.

On June 25, 2014, Bliss Communications announced that it would sell WBWI-FM and WBKV, along with WRJN and WVTY (then WEZY) in Racine.

WMBZ and co-owned 92.1 WVTY air separate commercials but have the same DJs and play the same country music.
