The South Umpqua River is a tributary of the Umpqua River, approximately 115 miles (185 km) long, in southwestern Oregon in the United States. It drains part of the Cascade Range east of Roseburg. The river passes through a remote canyon in its upper reaches then emerges in the populated South Umpqua Valley east of Canyonville.
