Chesapeake Bay The Chesapeake Bay ( ) is an estuary in the U.S. states of Maryland and Virginia, lying inland from the Atlantic Ocean and surrounded to the west by the North American mainland and to the east by the Delmarva Peninsula. It is the largest estuary in North America. With its northern portion in Maryland and the southern part in Virginia, the Chesapeake Bay is a very important feature for the ecology and economy of those two states, as well as others. More than 150 major rivers and streams flow into the Bay's 64299 sqmi drainage basin, which covers parts of six states (New York, Pennsylvania, Delaware, Maryland, Virginia and West Virginia) and all of Washington, D.C.
