Lotharingia (; ; ; ) was a short-lived medieval successor kingdom of the Carolingian Empire. It comprised present-day Lorraine (France), Luxembourg, Saarland (Germany), Netherlands, and the eastern half of Belgium, along with parts of today's North Rhine-Westphalia (Germany), Rhineland-Palatinate (Germany) and Nord (France). It was named after King Lothair II, who received this territory after his father Lothair I's kingdom of Middle Francia was divided among his three sons in 855.
