Palmarsh is a community (OS grid reference TR1333) in Folkestone and Hythe district, in the County of Kent, England. In origin it was a hamlet on the edge of the Romney Marsh, but modern development to the west of Hythe (mostly housing, together with some local shops) in a corridor along the A259 coastal road, has led to the joining together of the ancient town and cinque port of Hythe (to the east) and the rural hamlet of Palmarsh (to the west) in a single conurbation.
