Middle Francia () was an ephemeral Frankish kingdom that had no historical or ethnic identity to bind its varied peoples. It was created by the Treaty of Verdun in 843, which divided the Carolingian Empire among the sons of Louis the Pious. Situated between the realms of East and West Francia, Middle Francia comprised the Frankish territory between the rivers Rhine and Scheldt, the Frisian coast of the North Sea, the former Kingdom of Burgundy (except for a western portion, later known as "Bourgogne"), Provence and the Kingdom of Italy.
