Delintment Lake is an artificial lake about {{convert|33|mi}} northwest of Burns in the U.S. state of Oregon.{{cite web|title=Delintment Lake (Harney)|work=Atlas of Oregon Lakes|url=https://aol.research.pdx.edu/lakes/17120004001271|publisher=Portland State University|year=1985–2019|access-date=April 1, 2019}} Its name derives from that of homesteader F. S. De Lentiement, who in 1891 was granted ownership of a {{convert|160|acre|adj=on}} tract that included the land where the lake now stands.{{cite book |last1=McArthur|first1=Lewis A.|last2=McArthur|first2=Lewis L.|title=Oregon Geographic Names |edition=7th |location=Portland |publisher=Oregon Historical Society Press |date=2003 |pages=276–77|isbn=0-87595-277-1}}

The lake originated as a series of beaver ponds along Delintment Creek, a tributary of Silver Creek in Harney County. In 1940, the United States Forest Service combined and enlarged the ponds, and in 1953 local interest groups made further changes to improve conditions for fishing and other recreation. The dam that impounds the lake is {{convert|270|ft}} long and {{convert|20|ft}} high.

A Malheur National Forest campground with 29 campsites is adjacent to the lake. Activities include fishing, swimming, picnicking, and boating. Campground hosts are present during the summer.{{cite web|title=Delintment Lake Campground|url=https://www.fs.usda.gov/recarea/malheur/recarea/?recid=40044|publisher=U.S. Forest Service|year=2019|access-date=April 6, 2019}}
