Combe Down and Bathampton Down Quarries make up a 6.22 hectare Site of Special Scientific Interest (SSSI) in Bath and North East Somerset, England, important for its bat population. The disused quarries date from the 17th and 18th centuries and were the source of Bath stone for the city of Bath and elsewhere in the UK. A five-year project to stabilise the quarry workings was largely completed by November 2009.

Combe Down is a village on the outskirts of Bath, England, in the Bath and North East Somerset unitary authority area, within the ceremonial county of Somerset.
