Bardhyl or Bardhul is an Albanian masculine given name meaning 'the white/bright one', also reflected from the Illyrian name Bardylis and Messapic Barzidihi and Barduli. The same root is found in the Albanian given name Bardh-i (masculine) and Bardh-a (feminine), as well as in the Albanian surname Bardhi, meaning 'the white one'.
See also: Bardylis. The oldest attested variant of Bardhyl is Bardylis, the name of a 4th century BCE Illyrian king, and founder of the first attested Illyrian dynasty. The name was again carried by Bardylis' grandson, Bardylis II, son of Cleitus, who ruled from c. 295 to c. 290 BCE. Both were enemies of the Kingdom of Macedonia. Variant names are also attested in Messapic Barzidihi and Barduli in Apulia. The name contains the same root as the Albanian adjective i bardhë "white", ultimately from Proto-Indo-European *bʰór(h₁)ǵos < *bʰreh₁ǵ- ("to gleam, shine").
The name gained popularity among Albanians during the communist rule of Albania, serving as a more atheistic, and nationalistic identification.
The animal genus Bardylis (wasp) is named after Bardylis.
Bardhyl, Bardhyll, Bardhill, Bardhull and other variants are more popularly held by irreligious Albanians. Notable bearers include
