The Chewuch River is a river in the U.S. state of Washington.

Its name comes from the word /cwáx/ [čwáx] in the Columbia-Moses language meaning "creek".{{cite book|last=Bright|first=William|authorlink=William Bright|title=Native American placenames of the United States|url=https://books.google.com/books?id=5XfxzCm1qa4C&pg=PA95|accessdate=11 April 2011|year=2004|publisher=University of Oklahoma Press|isbn=978-0-8061-3598-4|page=95}}
