Francis, Duke of Saxe-Coburg-Saalfeld (in German and fully Franz Friedrich Anton, Herzog von Sachsen-Coburg-Saalfeld, 15 July 1750 – 9 December 1806), was a reigning Duke of Saxe-Coburg-Saalfeld, one of the ruling Thuringian dukes of the House of Wettin. As progenitor of a line of Coburg princes who, in the 19th and 20th centuries, ascended the thrones of several European realms, he is a patrilineal ancestor of the royal houses of Belgium and Bulgaria (and also of Portugal until the death of King Manuel II in 1932 and the United Kingdom until the death of Queen Elizabeth II in 2022), as well as of several queens consort and the empress consort of Mexico in the 1860s.
