KNWN-FM (97.7 MHz) is a commercial radio station licensed to Oakville, Washington, and serving the Seattle metropolitan area and the Olympic Peninsula.

[3] With its high power and tower at 701 meters (2,300 feet) in height above average terrain (HAAT), KNWN-FM covers Seattle, Tacoma and much of the Olympic Peninsula with a 60 dBμ signal.

[6] It later was granted a power boost and increase in its antenna height, allowing it to be heard in the more lucrative Seattle-Tacoma radio market.

In May 2009, while still owned by South Sound Broadcasting, the station began simulcasting KOMO, with Fisher Communications operating 97.7 FM under a local marketing agreement.

In June 2017, the outright sale of the station to the Sinclair Broadcast Group (which had acquired Fisher several years earlier) for $6.75 million was announced.
