Kent County is a county located in the U.S. state of Maryland, on its Eastern Shore. It was named for the county of Kent in England. Its county seat is Chestertown. As of the 2010 census, its population was 20,197. It is the least populous of Maryland's 23 counties.
In 1642, the governor and council appointed commissioners for the Isle and County of Kent. This act appears to have led to the establishment of Kent County.
The county has a number of properties which are listed on the National Register of Historic Places. A peninsula along the southern shore of the Sassafras River containing several large farms and a large pond that were assembled into one property by the former owners of The Sassafras Boat Company marina and Sassafras House restaurant at Georgetown, Liz Maytag and Mike Revuke, has been preserved as a wildlife sanctuary.
