Ebbsfleet Valley is a new town and redevelopment area in Kent, South East England, and part of the Thames Gateway, southwest of Gravesend. Development is coordinated by the Ebbsfleet Development Corporation. It is named after the valley of the Ebbsfleet River, which it straddles. Although a small part of the site in the east lies within the borough of Gravesham, Ebbsfleet Valley primarily sits in the borough of Dartford.
