The Chetco (Chetco: chit-dee-ni, chit-dee-ne ) are a tribe of Native Americans who originally lived along the lower Chetco River in Curry County in the U.S. state of Oregon. The name Chetco comes from the word meaning "close to the mouth of the stream" in their own language, which is part of the Athapascan languages. Although they were once one of the largest tribes on the Pacific coast of Oregon, "the last known full-blooded Chetco" died in 1940, and as of 2009 only 1500 or so descendants of the tribe remain. Some Chetco people are enrolled in federally recognized tribes, the Confederated Tribes of Siletz Indians in Oregon, and Cher-Ae Heights Indian Community of the Trinidad Rancheria, located in Humboldt County, California.
