The Loup River is a tributary of the Platte River located in central Nebraska, USA. It flows approximately 145 miles and is known for its winding path through the region's landscape. The river is significant for local agriculture and provides water for irrigation and livestock. The Loup River is part of the larger Missouri River watershed. It is divided into three main branches: the North Loup River, the South Loup River, and the Middle Loup River. These branches converge near the town of Fullerton, contributing to the river's overall flow and ecological diversity.
