Olasz is a Hungarian surname meaning "Italian" (someone of Italian origin). It derives from the Hungarian word olasz ('Italian'), itself from Old Slavic volxŭ 'Romance-speaker', which ultimately goes back to the Germanic term walha (cf. the root of English 'Welsh' and 'Walloon'). The same root appears in Hungarian Olaszország as the exonym for Italy. As an ethnonymic surname, Olasz originally identified a person of Italian descent or someone who had ties with Italy. Linguistically, it is a cognate of numerous European surnames that all go back to walha, including Walsh (Irish), Welch and Wallace (English/Scottish), Wallis (Scottish), and the Slavic Vlahović (Serbian) or Vlašić (Croatian). The variant Oláh is another form with a closely related meaning (originally 'Vlach' or 'Romanian'). Geographical distributionOlasz is also the name of a village in Baranya County, Hungary, whose toponym has the same etymology. As a surname, it is most frequent in Hungary, especially in counties with historical Italian influence or where exonyms were commonly used. The name belongs to the type of ethnic surnames found across the continent—often derived from how a community or its neighbours designated them. For Hungarians, olasz designated Italians, showing the enduring linguistic influence of the German walha on Finno-Ugric languages.
