KNKX (88.5 MHz) is a public radio station in Tacoma, Washington. A member of National Public Radio, it airs a jazz and news format for the Seattle metropolitan area. The station is owned by Friends of 88.5 FM, a community-based non-profit group. KNKX was established in 1966 as KPLU-FM by Pacific Lutheran University (PLU) before becoming an independent, community-licensed station in 2016. It is one of three full NPR member stations in the Seattle area, the others being KUOW-FM and KVTI, an outlet of Northwest Public Radio (though KVTI only provides grade B coverage of Seattle and can't be heard at all in most of Snohomish County because of interference from KSER).
