Big Kimshew Creek is a stream in Butte county northern California.

Its discharge fluctuates dramatically between spring, when it carries snowmelt, and autumn, ranging from 10 to 1,000 cubic feet per second (0.28 to 28.32 m3/s).

The creek rises in a meadow 1 mile (1.6 km) northwest of Table Mountain in the southern extreme of the national forest.

At the Little Kimshew confluence it turns west, then again southwest, through a valley over 1,200 feet (370 m) deep.

It is joined by Little Rock Creek just above the confluence with the West Branch Feather River.
