Shkije or Shkje, is a term used in the Gheg dialect of Albanian language to refer to Serbs, Macedonians, and Montenegrins, while the Albanian communities in Greece or Italy use it to refer to Greeks or Latins, or just non- Albanian speakers. The Arvanites in Greece use the version shkla to refer to the Greek population, while the Arbereshe in Italy, a substantial part of which originates from the Arvanites, use the words shklan and shklerisht which mean "that does not speak Arbereshe", or "that speaks an incomprehensible language", referring to the Latin languages. It is derived from either from the Venetian schiavone meaning the same or from the term " Slavs" , which contained the traditional meaning of “the neighbouring foreigner”.Pipa, Arshi (1989).

It was widely used in the Albanian literature as well, i.e. Lahuta e Malcís (1937) of Gjergj Fishta (1871–1940). Sami Frasheri also used the term in his works. During the Yugoslav wars, Albanian newspapers called Serbs "Shkja".
