Isfield is a small village and civil parish in the Wealden District of East Sussex in England, located north-east of Lewes.

[4] Local legend, as recalled by William Wratten, had it that King Harold spent the night before the Battle of Hastings in the village, at his demesne located where Isfield Place now stands.

Isfield became the home of John Shurley (died 1527), who was Cofferer of the Household to King Henry VIII.

Isfield Place is a 17th-century manor house, incorporating part of the original 16th-century mansion of the Shurley family.

The University of Sussex had a project to restore some of the brook meadows east of Vuggles and Bunce's Farms.

Just thirty years ago countless silvery Elvers (young Eels) rose up the Ouse weirs at Isfield, but they have long since gone due to pollution (nitrates, phosphates and trace chemicals) from farming and sewage with low flows from extraction and summer droughts.

[9] On the banks of the Isfield Weir to Rocky Wood there is archaic vegetation, such as dame's violet and hemlock.

Route 29 runs along the A26, serving Rose Hill and linking it every 30 minutes with Lewes and Brighton to the southwest and Uckfield, Crowborough and Tunbridge Wells to the northeast.
