Green Lake (Lushootseed: dxʷƛ̕əš) is a freshwater lake in north central Seattle, Washington, within Green Lake Park. The park is surrounded by the Green Lake neighborhood to the north and east, the Wallingford neighborhood to the south, the Phinney Ridge neighborhood to the west, and Woodland Park to the southwest.
