Honoré Théodore Paul Joseph d'Albert, 8th Duke of Luynes was a wealthy French nobleman and scholar. He is most remembered for the collection of exhibits he gave to the Cabinet des Médailles in 1862, and for supporting the exiled Comte de Chambord's claim to the throne of France. Throughout his life, D'Albert inherited a number of French titles, including Duke of Luynes, de Chevreuse, and de Chaulnes.

The Duke of Luynes is a territorial name belonging to the noble French house d'Albert. Luynes is, today, a commune of the Indre-et-Loire département in France. The family of Albert, which sprang from Thomas Alberti, seigneur de Boussargues, bailli of Viviers and Valence, and viguier of Bagnols and Pont-Saint-Esprit in Languedoc, acquired the estate of Luynes in the 16th century.
