Margaret of Geneva (1180?–1252), was a countess of Savoy by marriage to Thomas I of Savoy. She was the daughter of William I, Count of Geneva, and Beatrice de Faucigny (1160–1196).
Margaret was supposed to become the third wife of Philip II of France. However, when her father was escorting her to France in May 1195, Thomas I of Savoy carried her off. Attracted by her beauty, Count Thomas then married her himself, claiming that Philip II was already married (the French King had married Ingeborg of Denmark in 1193 but had repudiated her soon thereafter).

The children of Marguerite and Thomas I of Savoy were:
