The Maquoketa River is a tributary of the Mississippi River, approximately 150 miles (240 km) long, in northeastern Iowa in the United States. Its watershed covers 1,694 square miles (4,387 km2) within a rural region of rolling hills and farmland southwest of Dubuque. It is not to be confused with the Little Maquoketa River, another distinct direct tributary of the Upper Mississippi River meeting the Big River north of Dubuque. The river and its tributaries mark the border of the Driftless Area of Iowa, with the areas east of it not having been covered by ice during the last ice age. Its name derives from Maquaw-Autaw, which means "Bear River" in Meskwaki.
