The Confederated Tribes of the Chehalis Reservation is a federally recognized Indian Tribe located in rural southwest Washington State. The Chehalis Indian Tribe originally occupied a large area within the Chehalis River Basin stretching from the foothills of the Cascade Mountains to the Pacific Ocean. The tribe has been located on a reservation within the Chehalis River watershed since 1850, although important historic and archeological sites are scattered throughout the tribe’s aboriginal area.

The Chehalis Reservation is 4,438 acres large and the reservation was first established in 1860 for the Lower and Upper Chehalis people. Originally 4,224.63-acres large, 3,753.63 acres of land were distributed to non-native settlers through an 1866 Executive Order. An additional 471 acres were given to schools. More land was taken from the tribe.

The Confederated Tribes of the Chehalis Reservation’s headquarters is in Oakville, Washington. Chehalis is a collective name for several tribes that lived on the Chehalis River. The name “Chehalis” means sand, originally referring to a village near the present-day town of Westport, and later came to be applied to the river and the people living upriver.
The Chehalis did not sign a treaty but by executive order in 1864 land was set aside for a Chehalis Reservation. The Confederated Tribes of the Chehalis Reservation was formed and approved by the federal government in 1939 and its constitution was amended in 1973.
