Bunjevci (pronounced [bǔɲeːʋtsi] or [bǔːɲeːʋtsi]) are a South Slavic community and ethnic group living mostly in the Bačka region of Serbia (province of Vojvodina) and southern Hungary (Bács-Kiskun county, particularly in the Baja region). They presumably originate from western Herzegovina region, from where they migrated into the Dalmatia, and from there to Lika and Bačka in 16th and 17th century. Bunjevci who remained in the original areas in Bosnia and Herzegovina, as well as those in modern Croatia, today maintain the designation chiefly as an ethno-regional identity, and declare themselves as Croats. In Bunjevac-populated areas of Serbia, some people declaring themselves as Croat or Yugoslav are of Bunjevac ancestry.

Bunjevci are Roman Catholic, and speak with an Ikavian accent (Bunjevci dialect) with certain archaic characteristics. During the 18th and 19th century, they formed a sizable part of population of northern Bačka, but many of them were gradually assimilated into Hungarians, while some other adopted Croat or Serb identity.
