Enumclaw ( (listen) EE-nəm-klaw) is a city in King County, Washington, United States. The population was 10,669 at the 2010 census. The 2019 estimate is 12,190.
The Enumclaw Plateau, on which the city resides, was formed by a volcanic mudflow (lahar) from Mount Rainier approximately 5,700 years ago.
The name Enumclaw is derived from a Salish term that translates as "place of evil spirits", apparently referring to Enumclaw Mountain, located about 6 miles (9.7 km) to the north. The mountain's name was derived from an evil incident that occurred there or to the occasional powerful windstorms from the east that affect the region. Native American mythology tells the story of two brothers – Enumclaw and Kapoonis – who were turned into thunder and lightning, respectively, by their father. The City of Enumclaw says the name means "thundering noise".
One of the first white settlers in south King County was Allen L. Porter. In 1853, he claimed a 320-acre (1.3 km2) parcel on the White River, about three miles (5 km) west of the site of Enumclaw. He maintained a troubled relationship with the local Smalkamish tribe (some of the ancestors of the Muckleshoot tribe) for some time, and in 1855 his cabin was burned to the ground. Porter, who had been warned in advance by a friend in the tribe, hid in the woods until they had left.
