WMUV (100.7 FM) is a commercial Christian radio station licensed to Brunswick, Georgia, but it serves Jacksonville, Florida.

Studios are on Bonneval Road in the Southside district of Jacksonville, and its transmitter tower is in Kingsland, Georgia.

The station later began airing Christian radio programming as WBYB (1993–1995), classic rock as both WWRD (1995–1996) and WWRR Arrow 100.7 (1996–2005), and oldies as WKQL Kool 100.7 (2005–2006).

On October 20, 2006, WKQL became the eighth station in the United States to adopt the rhythmic hot AC MOViN' format and changed the call sign to WMUV.

On January 3, 2015, after being acquired by Chesapeake-Portsmouth Broadcasting, WMUV and sister station WSOS-FM flipped to Christian AC as The Promise.
