The Appoquinimink River is a river flowing to Delaware Bay in northern Delaware in the United States. The river is 15.3 miles (24.6 km) long[3] and drains an area of 47 square miles (120 km2) on the Atlantic Coastal Plain.

The Appoquinimink flows for its entire length in southern New Castle County. It rises approximately 2 miles (3 km) west of Townsend and flows generally eastwardly, south of Middletown and past Odessa, to its mouth at the northern end of Delaware Bay, approximately 3 miles (5 km) east of Odessa.[5] In its upper course the river passes through two man-made lakes, Wiggins Mill Pond[2] and Noxontown Lake;[6] the river is tidal to the dam at Noxontown Lake, and salinity from Delaware Bay typically affects the lowermost 5 miles (8 km) of the river.[7] The lower 7 miles (11 km) of the river are considered to be navigable by the U.S. Army Corps of Engineers.[8]

It collects three named tributaries along its course:[5] From the north, Deep Creek, 4.2 miles (6.8 km) long[4] (also known historically as the "North Appoquinimink River"[9]); and Drawyers Creek,[10] 8.2 miles (13.2 km) long;[4] and from the south, Hangmans Run.[11]

According to 2002 data from the United States Environmental Protection Agency, 54.9% of the Appoquinimink River watershed is occupied by agricultural uses (predominantly soybeans, corn, and wheat); 15.1% is residential; 9.9% is wetland; and 8.8% is forested.[12]

In 2004, a non-profit group, The Appoquinimink River Association, was founded with a mission to protect the water and natural resources in the region surrounding the Appoquinimink River.[13]
