North Santiam River
The North Santiam River is a tributary of the Santiam River in western Oregon in the United States. It drains of the Cascade Range on the eastern side of the Willamette Valley east of Salem.

It rises in the high Cascades in eastern Linn county, northwest of Three Fingered Jack in the Willamette National Forest. It flows north through the mountains past Marion Forks, receiving the drainage from the western slope of Mount Jefferson. Near Mount Jefferson it turns sharply west, descending through a canyon past Idanha and Detroit to Niagara County Park where the valley begins to widen and some agriculture use begins. Continuing west, the river flows past Gates, Mill City and Mehama. It emerges through the foothills into the Willamette Valley near Stayton, then flows southwest through the valley where it joins the South Santiam River to form the Santiam River. The confluence is approximately east of the confluence of the Santiam and the Willamette River.

It is impounded by Detroit Dam in the mountains west of Detroit to form Detroit Lake for flood control. Detroit Lake State Park is along the northern shore of the lake.

In the 19th century, the canyon of the North Santiam River provided a formidable obstacle to settlers. The construction of a railroad in 1887 opened up the canyon to settlement and logging of the surrounding mountains.
