Chilworth is a village in the Test Valley district of Hampshire, England, on the northern edge of Southampton. Good travel connections and restricted development have led to the village becoming particularly affluent. The village was referred to as Celeworda in the Domesday Book of 1086, and is now in two parts: modern Chilworth lying along the straight 'new' stretch of the Southampton to Romsey road, and old Chilworth built around the 'old' road.
