François Vincent Marc de Beauvau, 1st Prince of Craon (2 April 1676 - 10 March 1754),^[1] was a Lorrainese nobleman who served as viceroy of Tuscany.

Born in Nancy, the capital of the Duchy of Lorraine, he was the son of Louis, Marquis of Beauvau (1638–1703) and his second wife, Anne de Ligny.

On 16 December 1704 he married Anne Marguerite de Lignéville (1686–1772) at Lunéville. They had eight sons and 12 daughters. His wife Anne Marguerite was the mistress of his sovereign, Leopold, Duke of Lorraine. His sister, Catharine Diana de Beauveau, married the Irish Jacobite exile Owen O'Rourke.^[2]

He was governor of the regency council of the Grand Duchy of Tuscany for Grand Duke Francesco, later Francis I, Holy Roman Emperor, who had been declared successor of the last Medici ruler in the Treaty of Vienna. He administrated for this prince from 1737 to 1754, with the title of viceroy.

Having inherited the marquisate of Beauvau in Lorraine, he was created marquis of Craon on 21 August 1712 by Louis XIV of France.

On 13 November 1722 he became an honorary Prince of the Holy Roman Empire under the title "Prince von Craon".
