Anna Maria Luisa de' Medici (11 August 1667 – 18 February 1743) was a Tuscan noblewoman who was the last lineal descendant of the main branch of the House of Medici. A patron of the arts, she bequeathed the Medici's large art collection, including the contents of the Uffizi, Palazzo Pitti and the Medicean villas, which she inherited upon her brother Gian Gastone's death in 1737, and her Palatine treasures to the Tuscan state, on the condition that no part of it could be removed from "the Capital of the grand ducal State....[and from] the succession of His Serene Grand Duke."
