Kanaskat, Washington is an unincorporated community in King County, Washington, United States. Kanaskat was a small facility on the Northern Pacific Railway, today's BNSF Railway, created by the opening of a cut-off between Palmer, Washington and Auburn, Washington, built 1899-1900 by the Northern Pacific's contractors Horace C. Henry and his partner Nelson Bennett. Kanaskat served as a water-stop for steam-powered trains out of Auburn, as well as a small yard and scale for the NP's Green River Branch northward to Kangley, Washington, Selleck, Washington, and Kerriston, Washington, as well as the large mills located just to the south in Enumclaw, Washington and Buckley, Washington.
