Coombe Hill is a hill in The Chilterns, located next to the hamlet of Dunsmore, Buckinghamshire, England, near the small town of Wendover, and overlooking Aylesbury Vale. It is not to be confused with another Coombe Hill on the flank of Haddington Hill, some two miles to the north-east. It is part of the Bacombe and Coombe Hills Site of Special Scientific Interest.
