The North Fork Gunnison River (locally known as the North Fork) is a tributary of the Gunnison River, 33.5 miles (53.9 km) long,[4] in southwestern Colorado in the United States.

It drains part of the southwestern flank of the Elk Mountains northeast of Delta.

The confluence is located along State Highway 133 on the south side of McClure Pass.

It descends to the southwest through a widening valley past Somerset, Paonia, and Hotchkiss.

Modern coal mining operations are highly visible along the upper valley walls.
