Warlingham is a village in the Tandridge district of Surrey, England, 14.2 miles (22.9 km) south of the centre of London and 22.3 miles (35.9 km) east of the county town, Guildford. Warlingham is the centre of a civil parish that includes Hamsey Green, a contiguous, smaller settlement to the north. Caterham is the nearest town, 2.0 miles (3.2 km) to the southwest.
The name is probably derived from "The homestead (-ham) of the followers (-ing) of Waerla".
Flint implements are not uncommon, and reputed eoliths have been found in the pebble beds near the village centre. In 1909 several cinerary urns of late Celtic date were found near the road towards Worms Heath; one of them contained bones. In several places are depressions which may have been pit houses. Two of these are in the grounds of Bryn Cottage.
The village lay within the Anglo-Saxon administrative division of Tandridge hundred.
