Clear Creek (Ínaam in Karuk) is a tributary of the upper Sacramento River in northern California.

Clear Creek is the first major Sacramento River tributary downstream of the Shasta Dam.

Past the reservoir, the stream bed continues south until its confluence with the Sacramento River.

The Spring Creek Tunnel bypasses that section and delivers water from Whiskeytown Lake directly to Keswick Reservoir, both part of the Central Valley Project.
