History
The name derives from a word from a Native American language that means "land between two waters." Nassawadox is bounded on the east by the Atlantic Ocean and on the west by the Chesapeake Bay. The county is divided, as is the town, into bayside and seaside areas, which refer to the land on either side of the highway, Route 13 (Lankford Highway), which runs through Accomack and Northampton counties.
Highlighting its name and its location, Nassawadox has since 1993 hosted the annual October Between the Waters Bike Tour, which features bike tours of various lengths between the Eastern Shore's two coasts.
Brownsville and the Northampton Lumber Company Historic District are listed on the National Register of Historic Places.
