Chaldon is a village and civil parish in the Tandridge District of Surrey, England. The village is situated high on the North Downs, immediately west of Caterham and 15.8 miles (25.4 km) south of Charing Cross, the traditional centre of London.

Chalvedune is the first written record of the place in 675 AD, meaning the hill (down) where calves were pastured, in a grant of land to Chertsey Abbey. Prior to this period of human history, White Hill on the borders of Chaldon and Caterham has yielded neolithic flints.

The village lay within the Anglo-Saxon administrative division of Wallington hundred.

In the Domesday Book of 1086 the manor of Calvedone appears in Wallington hundred rendering £4 to its lord Ralph Fitz Turold, holding it as was most of the hundred of Bishop Odo of Bayeux. Prior to the Conquest it had been held by the Saxon lord Dernic of King Edward. It consisted of two hides, land for two lord's plough teams and a church. In medieval times the parish included a narrow strip of land below the southern foot of the Downs and a wedge of land to the north of the church that in the 19th century were transferred to Bletchingley and Coulsdon respectively – these are omitted from this article.

An inscribed stone dedicates a pond for use by residents not animals dated to the late 18th or early 19th century, which illustrates the lack of water in the village during summer months. St Catherine's south chancel chapel in the church became devoted to the memory of Christian Hane (d.1752) of an aedicular type with a white stone rectangular panel flanked by Doric pilasters with red marble inlay, swan-neck pediment and crowning shell.

The Grade I architecturally listed church of Saints Peter and Paul (built before 1086 AD) contains a large wall painting of around 1170 depicting images of the ways of salvation and damnation and their result.

Under Rev. James Legrew, the tithes were commuted for £335. 11s 3d, however as rector retaining a glebe of 31 acres, with a glebe house. A tower and spire were added to the church in 1843 from a bellcote before. Given its steep, dry landscape on top of the North Downs Area of Outstanding Natural Beauty, Chaldon did not develop new homes substantially even in the 19th and 20th centuries; though replacements to farmhouses were built in this period.

In 1848 the population was 197 and the population in 1901 was only 266 and it consisted of little more than "the church and six scattered farms". By 1911 Viscount Hylton connected his farms and cottages with the East Surrey Water Company's mains; otherwise the supply depended upon the shallow wells and ponds, filled in a wet season and empty in a dry one.

Chaldon has received by some locals the epithet "Little Switzerland" because of the microclimate resulting in heavier snowfall here than in other parts of the region when there is snow in Winter. Caterham-on-the-Hill is centred 1.5 miles (2.4 km) ENE of Chaldon and London is 15.8 miles (25.4 km) north.

The civil parish of Chaldon fell within the Reigate Poor Law Union upon its creation in 1837, subsequently coming under control of Reigate Rural Sanitary District from 1875 and Reigate Rural District from 1894 until its abolition in 1933. Thereafter it became part of the Caterham & Warlingham Urban District until 1 April 1974 when the major local government reorganisation brought Chaldon under the newly formed Tandridge District.

For the purposes of parliamentary elections, Chaldon became part of the Eastern Division of the Surrey county constituency upon its creation in 1832. It moved to the Mid Division in 1867, to the South Eastern Division in 1885, to the Reigate Division in 1918 and to the East Surrey Division in 1948 where it remains to this day.

Along the north street, Church Lane, is a line of houses ending with the Church Green. Here is a close cluster of five listed buildings including the two most highly ranked listed buildings plus farm outbuildings. This area forms a conservation area. Its booklet with hand-drawn illustrations was produced in 1975, year of European Architectural Heritage. On Roffes Lane at no. 18 and no. 20 are two unusual Arts and Crafts elm timber framed and panelled cottages by the architect Ernest George Trobridge. There was a third at no. 22; however, this was demolished in 2015 and no. 18 is under threat from developers.

See above.

This Grade II* listed timber-framed building was built in the 14th century and encased in brick and flint in the 18th century; its door is of the Tudor period. Its large gable ends have a large window housing a third floor; however, its extension at a right-angle has instead two taller storeys, slightly lower in height.

Although almost a plateau, the highest part of Chaldon is White Hill, which overlooks Caterham and southeast London beyond and is occupied by Surrey National Golf Course.
