Cublington is a village and one of 110 civil parishes within Aylesbury Vale district in Buckinghamshire, England. It is about seven miles (11 km) north of Aylesbury. The village name is Anglo Saxon in origin, and means 'Cubbel's estate'. In the Domesday Book of 1086 it was recorded as Coblincote.
The parish church of St Nicholas is built in the perpendicular style. The tower of the church is decorated with blank tracery windows. Inside, the chancel arch has unusual corbels of a man and a monkey. At one time there was also a Methodist Chapel in the village.
North west of the church the 18th century stable block of the former manor house survives, it is an impressive building built of brick. A granary also survives built on an arcaded basement. This is rare as granaries in the area tended to be built on saddle stones. This type of agricultural building was generally raised from the ground to deter rodents.
There are some houses of note, these include: Old Manor Farm, a large low house with a recently created series of spectacular gardens; and opposite the church, the former rectory, dating from the 18th century with more recent additions, and an informal garden, open to the public once or twice a year. Neales Farm is an H plan half-timbered house dating from circa 1600.
The village has many old cottages, as well as small enclaves of newly built houses.
In 1971, the Report of the Roskill Commission on the London Airport expansion selected Cublington as the location of a proposed third airport for London on the basis of Cost Benefit Analysis. One Commission member, planner Colin Buchanan, produced a dissenting report rejecting the proposal to build on Cublington as "an environmental disaster." The government later rejected the Roskill recommendation on environmental grounds, in favour of a site at Maplin Sands, Foulness.
The village pub is called "The Unicorn".
