Emmanuel Philibert, Duke of Savoy (July 8, 1528, Chambéry - August 30, 1580, Turin) was Duke of Savoy from 1553 to 1580.

Emmanuel Philibert's mother was sister-in-law to Charles V, Holy Roman Emperor, and the future duke served in Charles's army during the war against Francis I of France, distinguishing himself by capturing Hesdin in July 1553. A month later, he became duke on the death of his father, but this was a nearly empty honor, as the vast majority of his hereditary lands had been occupied and administered by the French since 1536. Instead, he continued to serve the Habsburgs in hopes of recovering his lands, and served Philip II as Governor of the Netherlands from 1555-59. In this capacity he personally led the Spanish invasion of northern France and won a brilliant victory at Saint-Quentin in August 1557. By the Peace of Cateau-Cambrésis between France and Spain, (1559) the duchy was restored to Emmanuel Philibert and he married Margaret of France, sister to King Henry II.

Emmanuel spent his rule regaining what had been lost in the costly wars with France. A skilled political strategist, he took advantage of various squabbles in Europe to slowly regain territroy from both the French and the Spanish, including the city of Turin. He also purchased two territories. Internally, he moved the capital of the duchy from Chambéry to Turin and replaced Latin as the duchy's official language with Italian. He was attempting to acquire the marquisate of Saluzzo when he died.
