Smederevo–Vršac dialect (Serbo-Croatian: Latin: Smederevsko-vršački dijalekat, Cyrillic: Смедеревско-вршачки дијалекат) a subdialect of the Shtokavian dialect of Serbo-Croatian. It is transitional between the Šumadija–Vojvodina dialect and the Kosovo–Resava dialect.
The dialect is mainly spoken in Serbia or more exactly in north-eastern part of Šumadija (between Smederevo and Kragujevac), part of Belgrade, western part of eastern Serbia around Požarevac and Veliko Gradište, and south-eastern part of Vojvodina (south-eastern Banat including the city of Vršac). Some of the speakers could be also found in eastern Banat, in Romania.
The Smederevo–Vršac dialect was formed as a mixed speech of populations that spoke Šumadija–Vojvodina and Kosovo–Resava dialects. It is, however, linguistically closer to the Kosovo–Resava dialect and it is sometimes classified as a sub-dialect of the Kosovo–Resava dialect.
In the past, Smederevo–Vršac dialect was spoken in much larger area. Some of the speakers of this dialect migrated to the vicinity of Gallipoli in Turkey (After the First World War they migrated to Macedonia).
