Duncton is a village and civil parish in the District of Chichester in West Sussex, England.

Duncton Mill at the foot of the South Downs escarpment was powered by a large spring flowing from the chalk strata.

A stable flow of water at a constant temperature throughout the year is ideal for its present use as a trout hatchery.

Compass Bus route 99 between Petworth and Chichester serves Duncton six days a week, from Monday to Saturday.

In 1864 George Wyndham, 1st Baron Leconfield, of Petworth House, commissioned a new parish church to be built on a more convenient site in the village.
