Mustafa Osman Alibegu, OSK, (1893, Ulqin – December 25, 1977, Shkodër) known as Cafo Beg Ulqini, was a soldier, nationalist and politician.

Originating from ancient Illyrian roots, the Ulqinaks were renowned sailors and, at times, pirates who terrorized the Adriatic, earning the moniker "Dulcignotes" in Italian documents during the Golden Age of Albanian piracy from the 16th to the 18th centuries.

However, with the end of the war and the establishment of the Serbo-Croatian-Slovenian Kingdom in 1918, the situation for Albanians outside their homeland became dire, marked by persecution, exile, and ethnic cleansing.

In response to these challenges, Cafo Beg Ulqini, serving as a sailor in the Yugoslav fleet, advocated for Albanian rights and joined the People's Radical Party in 1922.
