Helen of Anjou was a 13th-century queen consort of the Serbian Kingdom, married to King Stefan Uroš I. While her exact lineage remains a subject of historical debate, she is frequently associated with French or Angevin origins. After her husband's abdication, she served as a provincial governor for the regions of Zeta and Travunija during the reigns of her sons, Stefan Dragutin and Stefan Milutin. Later in life, she entered a religious order as a nun, leaving a significant cultural and religious legacy in the medieval Serbian state.
