The House of La Tour d'Auvergne (French: [la tuʁ dovɛʁɲ]) was an important French noble 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.
