Henfield is a large village and civil parish in the Horsham District of West Sussex, England.

It has a modern and intensely used village hall just off the High Street, the 13th-century St Peter's church, old inns, a wide and attractive common, and many interesting houses in private ownership.

The Cat House is at Pinchnose Green, so called because there used to be a tannery nearby and the process of tanning produces unpleasant odours.

This bird was killed by a cat belonging to the Anglican Canon Nathaniel Woodard who lived at nearby Martyn Lodge.

So incensed was Ward that he painted his house with pictures of a cat holding a bird that would be seen by the canon every time he walked past on his way to the church.

Henfield is home to the Sussex Wildlife Trust headquarters, four commons, brooks, moors and tributaries to the River Adur.

It covers almost 20 hectares, including a cricket pitch, two football fields, rich marshland and heathy grassland.

Lost species include small fleabane, starfruit, mudwort, lesser marshwort, bogbean, sundew, marsh cinquefoil, beaked and white sedges, chaffweed and bog-myrtle.

In 2017 disaster struck for the future of the botanical richness and the accompanying, often unseen, wildlife of the Common when the football pitches were sprayed with herbicide and ploughed destroying the glorious chamomile lawn and the recovering marsh vegetation.

It has many precious plants though including yellow flag, goat willow, meadowsweet, occasional marsh woundwort and even scarce meadow brome.

[13] Palmate newts are present in the ponds and the Common can still support a number of Birds of Conservation Concern including nightingale and cuckoo, and even lesser spotted woodpecker has been seen there.

In spring the brooks are full of life with marsh frogs, lapwings, reed buntings and traditionally the call of the cuckoo, although that is becoming rarer.

[13] Between Henfield Common and Woodmancote Place is a low plain with fine unimproved wet rush pastures known as The Moors.

Behind the Swains Farm shop, in the pony-grazed western fields there is the largest population of (and best managed) meadow thistle in Sussex.

[13] The Pokerlee Stream is a lovely tributary of the Adur that runs through the Beeding, Horton, and Dag brooks, south of Henfield, Nep Town and The Pools meadows and ends up going through a tiny triangular bluebell wood on the north side of Horn Lane.

It separates the Wealden Clay of Oreham from the fertile Greensand ridge's large arable fields.

[18] Henfield was the home of Colonel Henry Bishop, who was appointed Postmaster General by King Charles II in January 1660–61.

[citation needed] The eighteenth century botanist William Borrer, who specialised in the flora of the British Isles, was born and died in Henfield.
