La Tour d'Auvergne was a noble French dynasty. Its senior branch, extinct in 1501, held two of the last large fiefs acquired by the French crown, the counties of
Auvergne and
Boulogne, for about half a century. Its
cadet branch, extinct in 1802, ruled the
duchy of Bouillon in the
Southern Netherlands from 1594, and held the
dukedoms of
Albret and
Château-Thierry in the
peerage of France since 1660. The name was also borne by
Philippe d'Auvergne, an alleged collateral of the original Counts of Auvergne, and was adopted by the famous soldier
Théophile Corret de la Tour d'Auvergne, who descended from an illegitimate line of the family.
