Rushlake Green is a small village in the civil parish of Warbleton in the Wealden district of East Sussex, England.

The place-name Rushlake Green is derived from the Old English rysc lacu meaning rush watercourse, or watercourse where rushes grow.

Slightly east of Rushlake Green is a stream flowing into the Ashbourne, which may explain the place-name.

[1] Wealden iron was mined here and at nearby Warbleton in the 16th and 17th centuries.

[2] Earliest records of the village date back to the 16th century although the Grade II Listed Horse and Groom public house[3] and some cottages were built in the 17th century.
