Anna Maria Luisa de' Medici (11 August 1667 – 18 February 1743) was the last member of the senior branch of the House of Medici. Although her elderly father and childless brother tried to secure her succession to the Grand Duchy of Tuscany upon their own deaths, she was barred due to her gender, and so Tuscany was inherited by the Habsburgs.

In October 2012, it was announced that she would appear on a postage stamp. In celebration of this, the city council of Monteriggioni, in collaboration with local artists and craftsmen, established the Medici Week. The Week consisted of a series of events dedicated to Renaissance and contemporary art.
