The South Umpqua River is a tributary of the Umpqua River, approximately 115 miles (185 km) long, in southwestern Oregon in the United States.[4] 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.
