Joan of France (24 January 1391 – 27 September 1433) was Duchess of Brittany through her marriage to John VI. She was a daughter of Charles VI of France and his wife, Isabeau of Bavaria.

Abduction of John VI by the Counts of Penthièvre

The Counts of Penthièvre had lost the Breton War of Succession in the 1340s. As a result they lost the ducal title of Brittany to the Montforts. The conclusion to the conflict took many years to confirm until 1365 when the Treaty of Guérande was signed. Despite the military loss and the diplomatic treaty, the Counts of Penthièvre had not renounced their ducal claims to Brittany and continued to pursue them.

In 1420 they invited John VI to a festival held at Châtonceaux. John came and was arrested. The Counts of Penthiève then spread rumours of his death and moved him to a new prison each day. Joan of France called upon all the barons of Brittany to respond. They besieged all the castles of the Penthièvre family one by one.

Joan ended by seizing the dowager countess of Penthièvre, Margaret of Clisson, forcing her to have the duke freed.
