Sparks Lake is a natural body of water near the crest of the central Cascade Range in Deschutes County in the U.S. state of Oregon. The lake is about west-southwest of Bend along the Cascade Lakes Scenic Byway in Deschutes National Forest. Named for a 19th-century rancher, Lige Sparks, the water body is a remnant of a bigger lake that has partly filled with sediment and vegetation.
