The Coweeman River is a tributary of the Cowlitz River, in the South West corner of the U.S. state of Washington. Its name comes from the Cowlitz word ko-wee-na, meaning "short one", referring to a short Indian who once lived along the river.[2]
The Coweeman River originates in Coweeman Lake and flows west for 36miles to join the Cowlitz River near the confluence of the Cowlitz and Columbia River at Kelso.[1] Just below the mouth of its first named tributary, Butler Creek, the river drops over Washboard Falls.[1]
