William, Prince of Albania

Wilhelm, Prince of Albania (Wilhelm Friedrich Heinrich; Albanian: Vilhelm, Princ i Shqipërisë, 26 March 1876 – 18 April 1945) was sovereign of the Principality of Albania from 7 March to 3 September 1914. His reign officially came to an end on 31 January 1925, when the country was declared an Albanian Republic.

Outside the country and in diplomatic correspondence, he was styled "sovereign prince", but in Albania, he was referred to as mbret, or king.
