Devils Lake is a small lake in Lincoln County, Oregon, United States, along the Oregon Coast.
It separates the northern part of Lincoln City from the Central Oregon Coast Range. It is 1/3 of a mile wide, three miles (5 km) long, and up to 21 feet (6.4 m) deep. The 120 feet (37 m) long D River flows from the lake westward to the Pacific Ocean.
According to Oregon Geographic Names, the name derives from a Native American legend that a giant fish, giant octopus, or other large marine creature would occasionally surface, much to the dismay of anyone fishing in the vicinity.
