Waltham Cross is a town in the Borough of Broxbourne, Hertfordshire, England, located approximately 12 miles (20 km) north of central London. It is in the metropolitan area of London and the Greater London Urban Area.
The town is partly named for the Eleanor cross which stands in its centre, one of twelve constructed on the orders of Edward I following the death of his wife Eleanor of Castile in 1290. Only three of the original crosses remain intact, including the Waltham cross and two more in the Northamptonshire villages of Geddington and Hardingstone.
The town has a modest commercial centre, and is immediately north of the M25 motorway. Waltham Cross takes up a south-eastern corner of its county. The Waltham Cross post town stretches to the neighbouring town of Cheshunt and a small part of Enfield.
