KXKL-FM (105.1 MHz, "KOOL 105") is a classic hits station serving the Denver metropolitan area.

This station is licensed to Denver, Colorado and broadcasts with an ERP of 100 kW and is under ownership of Stan Kroenke's KSE Radio Ventures.

As KADX, the station had a MOR format that continued until it was sold to Columbine Broadcasting in 1973, who then flipped it to Jazz that same year.

By 1981, Great Empire Broadcasting added KADX to its portfolio, but would flip the station to Country in 1982 and take the call letters KBRQ, simulcasting its AM sister at 1280.

The radio station organizes the annual KOOL Concert, featuring live performances from artists from the genre.
