Crescent Lake is a natural lake on the eastern side of the Cascade Range Mountains in the northwest corner of Klamath County, Oregon, United States. The unincorporated community of Crescent Lake Junction on Oregon Route 58 and Crescent Lake State Airport are located 2.5 miles (4.0 km) northeast of the lake. The lake was named for its shape by Byron J. Pengra and W. H. Odell in July 1865.
