Margaret of Valois (, 14 May 1553 – 27 March 1615) was Queen of Navarre and of France during the late sixteenth century. She is also known as "Margaret of France" because she was a princess of France by birth, who later incidentally became Queen of France by marriage. Notably, she was the last surviving member of the House of Valois.
