The North Canadian River is a tributary of the Canadian River, approximately 441 miles (710 km) long, that flows through New Mexico, Texas and Oklahoma in the United States.

The North Canadian River rises just east of Des Moines, New Mexico in Union County, New Mexico, where it is known as Corrumpa Creek. From there it flows eastwardly through the Oklahoma Panhandle starting in Cimarron County, where it is also known for some distance as the Beaver River. It flows briefly into Sherman County in the Texas Panhandle for about 15 miles (24 km), then back to the Oklahoma Panhandle in Texas County, where it has a confluence with Coldwater Creek just above the dam at the Optima Lake project near Hardesty. Because the source of the river in this area is the Ogallala Aquifer, and because of increasing irrigation and other demands on said aquifer, the flow of the river in the Panhandle is light and intermittent, and the Optima Lake impoundment contains very little water. Below the dam, the river continues through the Oklahoma counties of Beaver and Harper before being joined in Woodward County by Wolf Creek just south of the town of Fort Supply, Oklahoma. It is dammed at Canton, Oklahoma in Blaine County where it forms Canton Lake. It flows past Oklahoma City, Oklahoma, joining the Canadian River in McIntosh County at Eufaula Lake.
