Banat is a geographical and historical region that straddles Central and Eastern Europe and which is currently divided among three countries: the eastern part lies in western Romania (the counties of Timiș, Caraș-Severin, Arad south of the Mureș river, and the western part of Mehedinți); the western part of Banat is in northeastern Serbia (mostly included in Vojvodina, except for a small part included in the Belgrade Region); and a small northern part lies within southeastern Hungary (Csongrád-Csanád County).

The region's historical ethnic diversity was severely affected by the events of World War II. Today, Banat is mostly populated by ethnic Romanians, Serbs and Hungarians, but small populations of other ethnic groups also live in the region. Nearly all are citizens of either Serbia, Romania or Hungary.
