List of princes of Galicia and Volhynia

This is a list of princes of Galicia (Halych or Halychyna) and its sister principality Volhynia (Volyn' or Volodymyr; Latin: Lodomeria). They were basically separate principalities (rulers being closely related), until Roman Mstislavich "the Great" united Halych and Volhynia in 1199.
