Jean VII d'Harcourt (1369 – 18 December 1452, Châtellerault) was a French nobleman. He was Count of Harcourt, Count of Aumale, Viscount of Châtellerault, and Seigneur of Mézières, of Elbeuf, of Lillebonne, of La Saussaye etc.
He was the son of John VI of Harcourt, Count of Harcourt, and of Catherine de Bourbon, sister-in-law of King Charles V of France. On 17 March 1390, he married Marie of Alençon (29 March 1373 – 1417), princess of the blood, daughter of Pierre II, Count of Alençon and of Marie Chamaillart d'Anthenaise, Viscountess of Beaumont. They had:
Jean VIII of Harcourt, Count of Aumale, lieutenant and captain general of Normandy, killed at the Battle of Verneuil.
Marie of Harcourt (1398–1476), wife of Antoine of Lorraine, Count of Vaudémont, who is the origin of the Harcourt-Lorraine branch.
Jeanne of Harcourt (1399–1456)
He participated in the siege of Taillebourg, where he was made a knight by his uncle Louis II, Duke of Bourbon, and at the siege of Tunis and Harfleur. He distinguished himself at the Battle of Agincourt in 1415, where he was taken prisoner.
In 1418, his castle at Harcourt was taken by the English. Through fear of king Henry of England, the count de Harcourt had retired within his castle of Aumale, with all his dependants; whither on a certain day, under the appearance of a visit to pay his compliments, came his cousin, Sir James de Harcourt, attended by about sixty combatants. He purposely dismounted at the gate of the castle, which, on his being recognised, was instantly opened, and every honour was paid him by the officers of the count. Part of his men entered with him, and he went to the count, who joyously received him, saying "Fair cousin, you are welcome." Sir James had ordered the remainder of his men to come to the castle when they had put up their horses in the town; and shortly after some conversation together respecting the wars now going on in France, seeing the opportunity was proper, Sir James took the count by the hand, and said "My lord, I make you a prisoner in the king's name."
