Jean-Baptiste Colbert, Marquess of Torcy (14 September 1665 – 2 September 1746), generally called Colbert de Torcy, was a French diplomat, who negotiated some of the most important treaties towards the end of Louis XIV's reign, notably the treaty (1700) that occasioned the War of the Spanish Succession (1701–1714), in which the dying Charles II of Spain named Louis XIV's grandson, Philippe, duc d'Anjou, heir to the Spanish throne, eventually founding the line of Spanish Bourbons.
