Walberton is a village and civil parish in the Arun District of West Sussex, England, 5 miles (8 km) north-west of Littlehampton, and south of the A27 road. The land rises from 33–115 feet (10–35 m) above sea level, a quarter of the height of Nore Hill, the nearest foothill of the South Downs, which is to the north of the parish. The parish includes the smaller village of Binsted to the east and the larger neighbourhood of Fontwell, less than two-thirds of a mile (1 km) to the north-west. Walberton has a medieval church next to its clustered centre. Binsted's medieval church retains an original setting of village houses dispersed over farm fields.

The two churchyards have yielded archaeological evidence that there was settlement during the Bronze Age, about 3,500 years ago. Some fragments of brick and tile were discovered at Binsted during excavations in 1992.

Walberton is listed in the Domesday Book of 1086 under the Hundred of Binsted (also called Avisford; called Binsted in 1086 but had its later name by 1166). It comprised 22 villagers, 17 cottagers and six slaves, plough land, woodland and meadows, as well as a church. Binsted itself was also listed as having 8 households.

The timber lychgate to the churchyard was installed as a war memorial in 1920.

The electoral ward named Walberton stretches north-east to Madehurst, with a total population taken at the 2011 census of 2,889.

Part of Binsted is within the South Downs National Park. The whole of Binsted's countryside was originally assessed by the Countryside Agency as meeting the criteria for inclusion.^{[citation needed]}

The space above the chancel of Walberton Church contains a colony of pipistrelle bats, which is counted annually. A figure of 300 has been recorded.

The local school is Walberton and Binsted CE Primary School. The present building is just over ten years old. There are seven classrooms, each of which has its own piece of garden. The school also offers ample play space, a music room and computer facilities.
