Cleawox Lake (klē' ə woks),[5] is a body of water dammed by sand dunes along the Pacific Ocean coast of the U.S. state of Oregon.

[2] Sharing the lakeshore are private properties as well as Oregon Dunes National Recreation Area and Jessie M. Honeyman Memorial State Park, which also partly fronts on Woahink Lake.

[5] Cleawox Lake is a submerged remnant of the headwaters of a small coastal stream that existed before the most recent ice age.

[2] Covering only 1.6 square miles (4.1 km2), Cleawox Lake's drainage basin is separate from the nearby Woahink–Siltcoos watershed to the east and south.

[2] Park visitors use the lake for swimming, canoeing, and fishing for warm-water species and rainbow and coastal cutthroat trout.
