KMSO (102.5 FM) is a silent commercial radio station in Missoula, Montana. The station last aired a Hot AC music format featuring Hot Hits. KMSO was locally owned, by Sheila Callahan & Friends, Incorporated, and serves Western Montana.

KUEZ began broadcasting in 1985. The station became KMSO when the call letters became available, as MSO is the airport code for Missoula. The station started out playing easy listening music. In the 90s it became The Point playing a mix between hot adult contemporary and adult alternative. In 1998, it would become Mountain FM. The station played adult hits with a lean towards adult top 40 at night. From 1998 to 2003 Mountain FM meandered between soft AC to Hot AC. It settled on Hot AC in early 2003. It would remain Hot AC for the remainder of its time on the air.

KMSO signed off the air on New Year's Eve 2024, as owner Sheila Callahan retired from radio broadcasting. Sister station KHDV, repeated on K279CP in Missoula, also signed off.
