Cuckfield is a large village and civil parish in the Mid Sussex District of West Sussex, England, on the southern slopes of the Weald. It lies south of London, north of Brighton, and east northeast of the county town of Chichester. Nearby towns include Haywards Heath to the southeast and Burgess Hill to the south. It is surrounded on some sides by Cuckfield Rural.
Before the modern local government system came into operation in the late 19th century it was described as being in the hundred of Buttinghill, in the rape of Lewes. The civil parish covers an area of 431.58 ha (1066 acres), and had a population of 3,266 persons in the 2001 census.
The origin of the name, Cuckfield (earlier spelled Kukefeld, Cucufeld, and Cucufelda), is debated but it is generally associated with the cuckoo which is the village emblem.
The village grew as a market town; and an important coaching stop between London and Brighton, since it lay on the turnpike. In 1820, 50 coaches a day were passing through; but when the railway to Brighton was to be constructed in the 1840s, local landowners objected to its projected route: it was therefore built through neighbouring Haywards Heath instead. The village lost its importance as a result. Today the A272 road also bypasses the village centre. It is however home to Warden Park Specialist School one of the main secondary schools serving the Haywards Heath area and to Holy Trinity Church of England Primary School, Cuckfield, one of the oldest schools in the United Kingdom.
It became an urban district in 1894 under the Local Government Act 1894, and was greatly enlarged in 1934 under a County Review Order by adding part of Chailey Rural District, Cuckfield Rural District (including the parish of Lindfield) and Haywards Heath Urban District.
The Parish Council, Cuckfield Museum and village library reside within the Queen's Hall, built in 1897 to celebrate Queen Victoria's Diamond Jubilee. The parish church, dedicated to the Holy Trinity, has Norman foundations, although the building itself is 13th century. The lych gates are listed buildings and several of the stained glass windows as well as the pulpit and the ceiling's painting were designed by Charles Eamer Kempe (1837–1907).
Gideon Mantell found the first known iguanodon fossils close to Cuckfield at Whitemans Green, where a monument to him now stands. He also features in the town's museum. Other attractions include the Elizabethan stately home, Cuckfield Park, to the west of the village. Cuckfield Park is reputedly hunted by its former resident Anne Pritchard Sergison, who was known to the locals as 'Wicked Dame Sergison', and who died in 1748. Bonfire Night celebrations are held here. Another Elizabethan house, Ockenden Manor, is a hotel and restaurant which has had one star from the Michelin Guide since 2001.
Cuckfield is also known locally for its idiosyncratic system of mayoral voting; unlimited numbers of votes can be purchased for the price of one penny each, with the winner receiving the most votes. The position is purely honorary and the money raised supports local charities.
