Honoré Caille, seigneur du Fourny (1630–1713) was a French genealogist.

An examiner at the Court of Accounts in Paris, he collected the papers of the noted genealogist Père Anselme after his death in 1694, and in 1712 published a new edition of Father Anselm's great work, the Histoire généalogique et chronologique de la maison royale de France, et des grands officiers de la couronne.^[1]

After his death, this work was continued by Father Angel of St. Rosalie (1655–1726) and Father Simplicien (1683–1759), both friars, like Father Anselm, at the Couvent des Petits Pères, a priory of the Discalced Augustinians in Paris attached to the Basilica of Our Lady of Victories.
