The Mispillion River is a river flowing to Delaware Bay in southern Delaware in the United States. It is approximately 15 miles (24 km) long and drains an area of 76 square miles (197 km²) on the Atlantic Coastal Plain.

It rises in northern Sussex County, approximately 3 miles (5 km) southwest of Milford, and flows generally east-northeastwardly, defining the boundary between Sussex and Kent counties; it passes through the center of Milford on its course to its mouth at Delaware Bay, 16 miles (26 km) northwest of Cape Henlopen. [3] [6] The lower 12 miles (19 km) of the river are considered by the U.S. Army Corps of Engineers to be navigable. [7]

A boardwalk known as the Mispillion Riverwalk follows the river in Milford. As of 2003, an effort was underway to preserve a greenway along the river upstream and downstream of Milford. [8]
