Cheshunt /ˈtʃɛzənt/ is a town in the Borough of Broxbourne, Hertfordshire, England with a population of around 52,000 according to the United Kingdom's 2001 Census. It is a dormitory town and part of the Greater London Urban Area and London commuter belt served by Cheshunt railway station. The town is located 13 miles (21 km) from Charing Cross, and 12 miles (19 km) from the City of London making it one of the closest parts of Hertfordshire to Central London.
The Prime Meridian passes to the east of Cheshunt.
The town name comes from the Old English name (as recorded in the Domesday Book) for the area, Cestrehunt, which probably refers to a "castle, erected by the Romans", the word cestre (along with the form ceastre), or even its modern forms, chester and caster being derived from the Latin castrum meaning "fort". This is commemorated in the arms of the former Cheshunt urban district council.
