The siege of Pouancé of 1432 (6 January – 22 February) was undertaken by John V, Duke of Brittany, against his nephew John II, Duke of Alençon, as part of a conflict involving the payment of a dowry. It is at times referred to as the third siege of Pouancé, in succession to other sieges in 1066 and 1379. Although the siege saw English and French forces fighting against each other, thus being able to set itself in the context of the Hundred Years' War, this conflict has its origins in a family dispute of financial nature.
