Matilda of Amboise (Mahaut, Mathilde d'Amboise; c. 1200 ‒ 12 May 1256) was the Countess of Chartres 1248-1256. She was the daughter of Sulpice III of Amboise and Isabella of Blois.[1]
She married Richard II, Vicomte de Beaumont,[2] but it seems they were childless. Richard died on 17 September 1242. In 1232 Matilda and Richard gave land to the nuns of Lieu.[3] Matilda later married Jean II de Nesle. She was also childless with him.
On Matilda’s death, her cousin John I, Count of Blois reunited Chartres with Blois.
