Cavenham is a village and civil parish in Suffolk, England, 10 kilometres (6 mi) northwest of Bury St Edmunds.

It is in the local government district of West Suffolk, and the electoral ward of Manor.

[3] The parish includes Cavenham Heath, a Site of Special Scientific Interest (SSSI) with a sand and gravel quarry close to it[4] and is the location of the Black Ditches, an Anglo-Saxon boundary ditch which is believed to be the most easterly of a series of early Anglo-Saxon defensive earthworks built across the Icknield Way.

Toponymists Keith Briggs and Kelly Kilpatrick say Cavenham means a man called Cafa once owned a homestead here.

They provide a number of different spellings following Domesday Book before it became stabilised as Cavenham.
