The Eastern Shore of Maryland is a part of the U.S. state of Maryland that lies predominantly on the east side of the Chesapeake Bay and consists of nine counties. As of the 2010 census, its population was 449,226, with just under 8 percent of Marylanders living in the region. The term “Eastern Shore” distinguishes a territorial part of the State of Maryland from the Western Shore of Maryland, land west of the Chesapeake Bay.
