Margaret of Anjou (1272 – 31 December 1299) was Countess of Anjou and Maine in her own right and Countess of Valois, Alençon and Perche by marriage. Margaret's father was King Charles II of Naples, whilst her husband was Charles, Count of Valois (third son of King Philip III of France), and her older brother was Saint Louis of Toulouse; her nephew was King Charles I of Hungary.
Margaret was a daughter of Charles II of Naples and his queen Mary of Hungary, the daughter of Stephen V of Hungary. Her father ceded to her husband, Charles of Valois, the Counties of Anjou and Maine as her dowry. She married Charles of Valois, a son of Philip III of France, at Corbeil on 16 August 1290. Their children included:
- Isabelle (1292–1309), wife of John III, Duke of Brittany
- Philip VI of France (c. 1293 - 1350)
- Joan of Valois
- Margaret of Valois (1295–1342)
