Bampton Castle was in the village of Bampton, Oxfordshire (). Differing accounts of its origin exist. One states that in about 1142 AD during the reign of Stephen, Matilda built a motte castle. Another states that in 1314–15, during the reign of Edward II, Aymer de Valence, Earl of Pembroke, obtained a license from the king to "make a castle of his house at Bampton." The castle was demolished before 1789 but parts of its structure have been incorporated into a house, Ham Court, which is a Grade II* listed building.
