Glenwood is an unincorporated community and census-designated place (CDP) in Klickitat County, Washington, United States.

An 1890 survey of the Yakama Reservation, accepted by the United States General Land Office, did not include the area known as "Tract-D".

Another 21,000 acres (85 km2) were part of the Gifford Pinchot National Forest administered by the United States Department of Agriculture.

After more than 100 years of dispute, in 1972 President Richard Nixon by Executive Order 11670 authorized the return of the 21,000 acre portion of Mt.

[8] In 2022, Klickitat County’s claim that Glenwood is not part of the Yakama reservation was rejected by the United States Supreme Court.
