Marc de Beauvau-Craon, prince de Craon

Marc de Beauvau, (François Vincent Marc; 29 April 1679 - 10 March 1754), Prince de Beauvau-Craon, was a Lorraine nobleman and viceroy of Tuscany.

Born in Nancy, the capital of the Duchy of Lorraine, he was the son of Louis, Marquis de 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.

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 de 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 Beauvau-Craon".

On 8 May 1727 he was made a grandee of Spain of the first class by Philip V, his son, Charles Juste, being admitted to the Honneurs de la Cour in Paris with the princely title in 1755.
