Northfleet is a town in the borough of Gravesham in Kent, England. It is located immediately west of Gravesend, and on the border with the Borough of Dartford. Northfleet has its own railway station on the North Kent Line, just east of Ebbsfleet International railway station on the High Speed 1 line.

Northfleet’s name is derived from being situated on the northern reach of what was once called the River Fleet (today known as the Ebbsfleet River). There is a village at the other end of the river named Southfleet. It has been the site of a settlement on the shore of the River Thames adjacent to Gravesend since Roman times. It was known as Fleote by the Saxons c. 600 AD, Flyote c. 900 AD, and Flete c. 1000 AD. It was recorded as Norfluet in the Domesday Book, and Northflet in 1201. By 1610 the name of Northfleet had become established. A battle took place during the Civil War at the Stonebridge over the Ebbsfleet river. Northfleet became a town in 1874 with Northfleet Urban District Council being established c. 1894. In 1974 it was merged with the adjacent Borough of Gravesend. The first council offices were off the Hill, but the council then moved to Northfleet House (now a nursing home for the elderly). Northfleet House was once the home of Thomas Sturge who owned a local cement works. Northfleet was in the lathe of Aylesford and the hundred of Toltingtrough.
