Prince Eugene Maurice of Savoy-Carignano (French: Eugène Maurice de Savoie-Carignan; 2 March 1635 – 6 June 1673) was a Franco-Italian nobleman and general. A Count of Soissons, he was the father of Imperial field marshal Prince Eugene of Savoy.
Eugene Maurice was born in Chambéry, Savoy. He was son of Thomas Francis, Prince of Carignano and Marie de Bourbon, Countess of Soissons. He was grandson of Charles Emmanuel I, Duke of Savoy and Catherine Micaela of Austria.
On 21 February 1657 he married the "beautiful and witty" Olimpia Mancini, a niece of cardinal Mazarin, daughter of Michele Mancini and Geronima Mazarini.
He obtained high military posts through his wife's influence. He played a role in defeating the Spaniards at the battle of the Dunes in 1658. He took part in the campaigns at Flanders (1667), Franche-Comté (1668) and Holland (1672); and was present as ambassador extraordinary of France at the coronation of Charles II of England.
He died at Unna in Westphalia in 1673, out of a deadly fever, although there were voices that he had been poisoned.
