The Confederated Tribes of the Coos, Lower Umpqua and Siuslaw Indians of Oregon are a federally recognized Native American tribe of Hanis Coos, Miluk Coos, Lower Umpqua (or Kuitsh), and Siuslaw people in Oregon.  They are indigenous peoples of the Plateau.
The Confederated Tribes of the Coos, Lower Umpqua and Siuslaw Indians are headquartered in Coos Bay, Oregon. The tribe is governed by a democratically elected general council, serving four-year terms. The tribal chief serves ten-year terms. The current administration is as follows:
- Chief: Warren Brainard
- Chairman: Mark Ingersoll
- Vice-Chairman: Teresa Spangler
- Councilperson: Debbie Bossley
- Councilperson: Doc (Don) Slyter
- Councilperson: Doug Barrett
- Councilperson: Josh Davies 
Members of the Confederated Tribes of Coos, Lower Umpqua and Siuslaw speak English. Formerly they spoke the Coos language and Siuslaw language (Siuslaw and Kuitsh dialects), which is a language isolate.  The tribe runs a language program to revive Coos and Siuslaw. 
The Confederated Tribes of Coos, Lower Umpqua and Siuslaw owns and operates:
- Three Rivers Resort, a Class 3 Facility in Florence, Oregon. 
- Three Rivers Casino, a Class 2 Facility in the Empire District of Coos Bay, Oregon.
- Blue Earth Services and Technology
The tribes did not have contact with Europeans until 1792. In 1828, Lower Umpqua (Kuitsh) people massacred members of the Jedediah Smith Party and attacked the Hudson's Bay Company's fort in 1838.  Most of their population died in the epidemics which followed European contact. 
In 1860 the remnants of these and other tribes were forced onto the Siletz Reservation. The reservation was split into three parts, with one section being opened to non-native settlement and another becoming the Alsea Reservation, which was opened to non-native settlement in 1875.
