Anne de Laval (1385 – 25 January 1466) was a medieval French noblewoman. She was the daughter of Jeanne de Laval-Tinténiac and her second husband Guy XII de Laval (died 1412), governor of Brittany and baron of Laval (Jeanne's first husband had been Bertrand du Guesclin).
She was the hereditary dame of Laval, hereditary baronne of Vitré, hereditary countess of Rennes, of Châtillon, of Gavre, of Acquigny, of Aubigné, Courbeveille, hereditary dame of Tinténiac, of Bécherel and of Romillé. She inherited all these titles from the successive accidental deaths of her two brothers, Guy and Francois.
On 22 January 1404, as daughter and sole heir of Guy XII de Laval, she married Jean de Montfort, lord of Montfort and of Kergolay, and from them were descended several bishops and the greatest lords of Brittany.
One of the conditions of the marriage was that any children born to it would bear the name and arms of Laval. (The same condition had already been applied to the marriage of Emma de Laval with Mathieu II de Montmorency.) Nevertheless, Jean de Montfort renounced the name and title he had been born with to take up the name of Guy XIII de Laval, better to associate himself with his wife Anne's power. Guy and Anne had 5 children:
