Debeljača (Serbian Cyrillic: Дебељача, pronounced [dɛbɛ̌ʎat͡ʃa]; Hungarian: Torontálvásárhely) is a town in Serbia.

After the end of the armed conflicts, a significant portion of the Hungarian population returned to the settlement, forming a new ethnic structure with the local inhabitants.

Since then, Debeljača has been home to the largest number of Hungarians, followed by Serbs and other ethnic groups.

The Debeljača was where the command of the German Banat Border Regiment was established, marking the rapid development of the area.

After 11 years, on February 26, 1873, Debeljača gained the right to hold annual large fairs and the status of a town.
