Apishapa River is a 139-mile-long (224 km)[2] tributary of the Arkansas River that flows from a source near West Spanish Peak in southern Colorado.

It joins the Arkansas east of Fowler, Colorado.

A U.S. Geological Survey (USGS) station, #07119500, located along this river near Fowler measures the river's discharge.
