WUOL-FM (90.5 FM, "Classical 90.5") is a 24-hour listener-supported noncommercial radio station in Louisville, Kentucky, broadcasting a classical music format. It began broadcasting in December 1976 as part of the University of Louisville.

WUOL, along with its sister stations WFPL and WFPK, broadcasts an HD Radio signal. All three stations have been licensed to the Louisville Public Media consortium (formerly Public Radio Partnership) since 1993. Prior to the university giving the station out and being a member of the Partnership, WUOL unintentionally competed with WFPK for the local audience for classical music.

The station was reassigned the WUOL-FM call letters by the Federal Communications Commission on March 19, 1982.
