Rusyns, also known as Carpatho-Rusyns, Carpatho-Russians, Ruthenians, or Rusnaks, are an East Slavic ethnic group from the Eastern Carpathians in Central and Eastern Europe. They speak Rusyn, an East Slavic language variety, treated variously as either a distinct language or a dialect of the Ukrainian language. As traditional adherents of Eastern Christianity, the majority of Rusyns are Eastern Catholics, though a minority of Rusyns practice Eastern Orthodoxy.
Rusyns primarily self-identify as a distinct ethnic group and are recognized as such in all countries where they exist, with the exception of Ukraine, which officially classifies Rusyns as a sub-group of Ukrainians. In Croatia, Hungary, Poland, Romania, Serbia, and Slovakia, Rusyns have official minority status. Some Rusyns identify more closely with their country of residence (e.g. Polish, Slovak), while others self-identify as a branch of the Ukrainian people.
