Bački Jarak (Serbian Cyrillic: Бачки Јарак) is a town located in the Temerin municipality, in the South Bačka District of Serbia.

Its name is derived from Serbian noun jarak (coming from Turkish ark;[1][2] "ditch" or "trench" in English), while adjective bački refers to its location in the region of Bačka.

The modern settlement was founded and settled by Evangelical Protestant ethnic Germans (Danube Swabians)[3] in 1787 (before that, the place used to be barren area).

After prison camps were dissolved (in 1946), most of the remaining German population left Yugoslavia in subsequent decades, mainly because of economic reasons.

In 1946–1947, Bački Jarak was settled by (mainly ethnic Serb) migrants from Bosnia and Herzegovina (Bosnian Krajina) and Croatia (Lika).
