Ambroise de Loré (1396, château de Loré, Oisseau – May 24, 1446, Paris) was baron of Ivry in Normandy, a French military commander, and companion of Joan of Arc. A reforming commisar of trades and police and "Garde de la prévôté de Paris" (guard of the provost of Paris), he became Provost of Paris from 1436 to 1446. He also fought at the battles of Agincourt, la Brossinière, Orleans and Patay.
He was born at the Chateau de Lore in Oisseau (Mayenne). His first exploit in arms was at the battle of Agincourt in 1415; he followed the party of the Armagnacs and attached himself to the Dauphin Charles. He waged continual warfare against the English in Maine until the advent of Joan of Arc. He fought at Jargeau, at Meung-sur-Loire and at Patay (1429).
Using his fortress of Saint-Céneri as a base of operations during the next few years, he seized upon Matthew Gough near Vivoin in 1431, and made an incursion as far as the walls of Caen, whence he brought away three thousand prisoners. Taken captive himself in 1433, he was exchanged for John Talbot, 1st Earl of Shrewsbury. In 1435 he and Jean de Dunois defeated the English near Meulan, and in 1436 he helped the Constable of France, Arthur de Richemont, to expel them from Paris.
