Loon Lake is a 294acres lake in Douglas County in the Oregon Coast Range of the United States, 15miles east-southeast of Reedsport, Oregon, at an elevation of 392feet. The lake is about 2miles long with a maximum width of about 0.4miles, and is over 100feet deep in some places.
The lake is "a classic example of a landslide lake", dammed by a slide of sandstone blocks which fell into the Lake Creek valley about 1,400 years ago. The lake was discovered in 1852 and named for the loons found on its waters.
