KLEF (98.1 FM) is a commercial classical music radio station in Anchorage, Alaska, United States. It is owned by Chinook Concert Broadcasters and operates from studios located on 65th Avenue. It is one of the last commercial classical music stations operating in the United States.

Northern Way Broadcasting, Inc., was granted a construction permit to build a new radio station on 98.1 MHz in Anchorage on December 15, 1986, after settling with two other applicants for the frequency. However, before construction, Northern Way sold the permit in 1987 to Chinook Concert Broadcasters. Chinook Concert was owned by Rick Goodfellow along with seven California families and one in Sitka, Alaska, and the station was consulted by Ed Davis, one of the founders and owners of KDFC in San Francisco. Davis, intrigued by the idea of a classical music station in Alaska, contributed technical expertise and also recruited most of the investors. KLEF began broadcasting on September 16, 1988, with Beethoven's Symphony No. 9 and Variations on the Alaska Flag Song by local composer Paul Rosenthal as the first selections played.
