Pedro de Alcántara Téllez-Girón y Beaufort Spontin, 14th Duke of the Infantado

Pedro Alcántara Álvarez de Toledo y Silva (10 September 1810 — 29 September 1844), was a Spanish noble from the House of Osuna. He was the 14th Duke of the Infantado, the 11th Duke of Osuna and the holder of various titles associated with those Dukedoms.

Pedro was the son of Francisco Téllez-Girón, 10th Duke de Osuna, the 10th Duke of Osuna, and of María Francisca de Beaufort Spontin y Toledo. The Téllez-Girón family had held title over the Dukedom of Osuna since 1562 with the rise of Pedro Téllez-Girón.

Pedro inherited the Dukedom of Osuna after the death of his father in 1820.

He died in 1844 without leaving behind any heirs. As a result, all of his titles, including the Dukedoms of the Infantado and of Osuna would pass on to his brother, Mariano Téllez-Girón y Beaufort Spontin.
