The Duchy of Gascony or Duchy of Vasconia^[2] was a duchy located in present-day southwestern France and northeastern Spain, an area encompassing the modern region of Gascony. The Duchy of Gascony, then known as Wasconia, was originally a Frankish march formed to hold sway over the Basques. However, the duchy went through different periods, from its early years with its distinctively Basque element to the merger in personal union with the Duchy of Aquitaine to the later period as a dependency of the Plantagenet kings of England.

In the Hundred Years' War, Charles V of France conquered most of Gascony by 1380, and under Charles VII of France it was incorporated into the Kingdom of France in its entirety in 1453. The corresponding portion within the Iberian Peninsula became the Kingdom of Navarre.
