Lodomeria (, ; ) is the Latinized name of Volodymyria, a synonymous term for the historical region of Volhynia, centered during the Middle Ages in the city of Volodymyr (Old Slavic: , ). After the capital city, the medieval Principality of Volhynia in the Kievan Rus' was also known as the Principality of Volodymyr-in-Volhynia, and on those grounds a Latin term was coined, rendering as Lodomeria (or Ladomeria, Ladimeria, Ladimiria, Vladimiria). The most prominent use of those Latin terms during the medieval times were attested in royal titles of Hungarian kings, since the reign of king Andrew II (1205-1235), who was styled as King of Galicia and Lodomeria, thus expressing pretensions on supreme rule over those regions. Since both Galicia and Lodomeria (Volhynia) where thus included among the lands of the Hungarian Crown, those titles were used by Hungarian kings up to 1918.
