Urban Jarnik (11 May 1784 – 11 June 1844) was a Carinthian Slovene priest, historian, poet, linguist, author and ethnographer.
He served as a parish priest in several villages and towns throughout southern Carinthia, including Klagenfurt and Moosburg, which at the time still had a large Slovene-speaking population.
Living among the Slovenian-speaking populations, Jarnik developed an interest in the many Slovenian dialects spoken in the era.
In his numerous articles, he wrote about the customs and rural cultural traditions of the local Slovenes.
He strongly influenced later generations of Slovenian ethnologists, folklore collectors, and philologists who lived or worked in Carinthia, such as Anton Janežič, Matija Majar, Matija Ahacel, and Anton Martin Slomšek.
