Alessandro Albani (15 October 1692 – 11 December 1779) was a leading collector of antiquities in Rome and a commissioner of works of art. He supported the art historian, Johann Joachim Winckelmann and commissioned paintings from Anton Raphael Mengs. As a Roman Catholic cardinal (from 1721) he furthered the interests of the governments of Austria, Savoy and Britain against those of France and Spain.
