Ashburnham is a civil parish in the Rother district of East Sussex, England, situated to the west of Battle.

It comprises 100.7 hectares (249 acres) ancient woodland and medieval deer park, containing a wide spread of flora and avian fauna.

[2] In 1767 the 2nd Earl of Ashburnham commissioned Lancelot ("Capability") Brown to remodel the park which he did by including three large lakes.

Several features of the old iron industry can be found along the track from the hamlet of Ashburnham Forge up to the furnace site near Lakehurst Lane.

[9] In the May 2023 election the ward was won by the Liberal Democrat candidate, who defeated the incumbent Conservative councillor.

Prior to Brexit in 2020, the villages were part of the South East England constituency in the European Parliament.
