Louise of Tuscany (2 September 1870 in Salzburg – 23 March 1947 in Brussels), was by marriage Crown Princess of Saxony as the wife of the future King Frederick Augustus III.

Louise was born on 2 September 1870 as the second child of Ferdinand IV, the last Grand Duke of Tuscany and his second wife, Princess Alice of Bourbon-Parma. Her full name and titles are: Luise Antoinette Maria Theresia Josepha Johanna Leopoldine Caroline Ferdinande Alice Ernestine, Princess Imperial and Archduchess of Austria, Princess of Tuscany, Hungary and Bohemia. Through her mother, she was a great-great-granddaughter of Charles X of France.

The 17-year-old princess attracted the attention of potential suitors, like Prince Pedro Augusto of Saxe-Coburg and Gotha (grandson of Emperor Pedro II of Brazil) or Prince Ferdinand of Bulgaria, but none of them found favor in the eyes of the spoiled Louise. Finally, in the summer of 1887 at Pillnitz Castle she met Prince Frederick Augustus of Saxony (eldest son of Prince George, who became in King of Saxony in June 1902). They married at Vienna on 21 November 1891, in a lavish ceremony which cost the groom the sum of 20,000 marks. In return, Louise fulfilled her royal duties, and bore him six children; however, she did not follow etiquette at the strict Dresden court, which resulted in arguments with her father-in-law, the Interior Minister Georg von Metzsch-Reichenbach and especially with her sister-in-law Princess Mathilde.
