Buncton (/ˈbʌntən, ˈbʌŋktən/) is a small village in the Horsham District of West Sussex, England, part of the civil parish of Wiston 0.5 miles (0.80 km) north.

Buncton existed as a settlement at the time of the Domesday survey in 1086, when it was called Bongetune.

[1][2] Its origins lie in a manor whose land lay within two exclaves of the parish of Ashington within the Rape of Bramber, one of the six ancient subdivisions of Sussex.

[4] This 11th or 12th century structure is composed mainly of flint and rubble masonry with some fragments of tile salvaged from the earlier Roman building that existed nearby.

The church contained a curious carving, claimed by some to be an example of a sheela-na-gig, which was destroyed by an act of vandalism in 2004.
