The Sycan River is a tributary, about 75 miles (121 km) long, of the Sprague River in the U.S. state of Oregon. The headwaters are in highlands in the Fremont National Forest south of Summer Lake. The river runs northwest into the Sycan Marsh in southern Lake County, from which it flows generally southwest to join the Sprague River near Beatty, in Klamath County. The uppermost 59 miles (95 km) of the stream are part of the National Wild and Scenic Rivers System.
