The Clatsop are a Chinookan-speaking Indigenous people of the Pacific Northwest of the United States. In the early 19th century they inhabited an area of the northwestern coast of present-day Oregon from the mouth of the Columbia River south to Tillamook Head, Oregon. Today, Clatsop descendants are members of the federally recognized Confederated Tribes of Siletz Indians, as well as the unrecognized Chinook Indian Nation and Clatsop-Nehalem Confederated Tribes.
