Don Carlos de Borbón y Austria-Este (Spanish: Carlos María de los Dolores Juan Isidro José Francisco Quirico Antonio Miguel Gabriel Rafael; French: Charles Marie des Douleurs Jean Isidore Joseph François Cyr Antoine Michel Gabriel Raphaël; 30 March 1848 – 18 July 1909) was the Carlist claimant to the throne of Spain as Carlos VII from 1868 (his father's Spanish renunciation), and holder of the Legitimist claim to the throne of France under the name Charles XI after the death of his father in 1887.

Carlos was born in Ljubljana, the capital of Carniola in what is now Slovenia, the elder son of Juan de Borbón y Braganza and of his wife Maria Beatrix of Austria-Este.

His name in full was Carlos María de los Dolores Juan Isidro José Francisco Quirico Antonio Miguel Gabriel Rafael.

After their father, considered too liberal for Carlist tastes, left their mother, the boys lived with her in Modena.

Her brother Francis V, Duke of Modena was largely responsible for the education of the boys and was the chief influence in their early lives.
