The Middle Santiam River is a tributary of the South Santiam River, approximately 35 mi (56 km) long, in western Oregon in the United States. It drains a remote area of the Cascade Range east of Corvallis in the watershed of the Willamette River.
It rises in the Cascades in eastern Linn County in the Willamette National Forest. It flows briefly north, then generally west and southwest through the mountains. In central Linn County it is impounded at the Green Peter Dam to form the Green Peter Lake reservoir. Approximately 4 mi (6 km) downstream from the dam it joins the South Santiam from the northeast as a arm of the Foster Lake reservoir.
