Slinfold is a village and civil parish in the Horsham District of West Sussex, England.
The village is almost 4 miles (6.4 km) west of Horsham, just off the A29 road.
The parish covers 4,186 acres (1,694 ha). The 2001 Census recorded a population of 1,647 people living in 627 households of whom 780 were economically active.
Slinfold is the source of the western River Adur, which flows to the English Channel at Shoreham-by-Sea
There has been a house at Dedisham, 1 mile (1.6 km) northeast of the village, since at least 1271, when Henry III granted the then occupier a licence to crenellate the manor house then on the site. The present house on the site appears to date from the 16th or 17th century. During the English Civil War the Parliamentarian commander Sir William Waller sacked a house on this site in 1643.
Slinfold Manor, 1.5 miles (2.4 km) south of the village, is a Georgian house built late in the 18th century.
