Loon Lake is a 294-acre (119 ha)[1] lake in Douglas County in the Oregon Coast Range of the United States, 15 miles (24 km) east-southeast of Reedsport, Oregon, at an elevation of 392 feet (119 m).[2] The lake is about 2 miles (3 km) long with a maximum width of about 0.4 miles (0.6 km), and is over 100 feet (30 m) deep in some places.

The lake is "a classic example of a landslide lake",[1] 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.
