Burton Mill Pond, located just south of Petworth in West Sussex, is a historic millpond whose water power once drove an 18th-century corn mill, now a private residence.

The site is a nationally important freshwater and wetland habitat, rich in birdlife and aquatic vegetation, with viewing platforms offering close-up perspectives over the water and reedbeds.

A roughly 3-mile circular nature trail begins at the car park and passes through varied habitats including woodland, wetland, and boardwalked sections over the dampest ground. A shorter easy-access trail of around 400 metres is suitable for wheelchairs.

The pond is twinned with nearby Chingford Pond, and the long-distance Serpent Trail can be joined from here via public rights of way. Visitors are asked to stay on footpaths to protect the fragile wetland plant communities.
