Stifford is an area in the town of Grays in the borough of Thurrock in Essex, England. Stifford was historically a parish; the parish was abolished for civil purposes in 1936 when Stifford became part of Thurrock. Stifford is in two main parts: the original village, now known as North Stifford, lies to the north of the modern A13 dual carriageway. South Stifford is a largely residential area south of the A13 and to the west of Grays town centre. Stifford also gives its name to the Stifford Clays housing estate to the north of Grays.
