WOKI (98.7 FM) is a commercial radio station licensed to Oliver Springs, Tennessee, and serving the Knoxville metropolitan area.

The transmitter is on Granville Lane in Heiskell, Tennessee, using a tower about twenty miles northwest of Knoxville.

Late mornings feature Bob Yarbrough with Hallerin Hilton Hill heard in afternoon drive time.

The rest of the weekday schedule is made up of nationally syndicated conservative talk shows, mostly from co-owned Westwood One: Dan Bongino, Mark Levin and Red Eye Radio.

WOKI-FM, previously on the 100,000-watt 100.3 FM frequency in Oak Ridge, Tennessee, began in 1974 with a progressive rock format using automated announcements.

By the late 1970s it had switched to successful Top-40 format mixed with some southern and hard rock, and live disc jockeys.

After the early 1980s, WOKI dropped the hard and southern rock and sports, and became strictly a mainstream Top 40 station thru 1993, broadcasting as "FM 100", "Hits 100", and "I-100".

On July 7, 2010, Oak Ridge FM announced plans for WNOX to stay with its talk format but with different hosts.

After filing for bankruptcy, Citadel Broadcasting ended its lease agreement with Oak Ridge FM, Inc. for the 100.3 WNOX frequency two years early.
