The North Fork Republican River is a 55.4-mile-long (89.2 km)^[2] tributary of the Republican River. It flows eastward from a source in Yuma County, Colorado to just north of Haigler in Dundy County, Nebraska. There it joins with the Arikaree River to form the Republican River.

The North Fork Republican River drains an area of 5,086 square miles (13,170 km²), including 4,449 square miles (11,520 km²), or 87.5%, in eastern Colorado, 575 square miles (1,490 km²), or 11.3%, in southwestern Nebraska, and 62 square miles (160 km²), or 1.2%, in northwestern Kansas.^[3]
