Agnes of Périgord (died 1345) was Duchess consort of Durazzo, through her marriage to John of Gravina, Duke of Durazzo, who was also the ruler of the Kingdom of Albania. Although Agnes was never styled as Queen consort, she became politically influential. Following the death of Robert, King of Naples in 1343, she organised a marriage for her eldest son to Robert's granddaughter, who was second-in-line to the Neapolitan throne. Agnes's ambition was to bring her family closer to the line of succession.
