Pančevački Rit (Панчевачки рит) is a small geographical area in south-western Banat, Serbia. It is situated between the rivers Danube and Tamiš, in Belgrade's municipality of Palilula.
Its wetland was constantly flooded, but since World War II it has been drained part by part and almost half of it has been turned into a very fertile patch of land, suitable especially for cultivating grains and vegetables. It is managed by Serbia's largest agricultural company, "PKB Beograd", which almost exclusively provides food for 2 million people in the greater Belgrade area; thus Pančevački Rit is commonly nicknamed Granary of Belgrade. Stockbreeding is also very intensive, as are fishery and hunting.
Many meandering canals and bogs have remained in the marsh: the slow streams of Vizelj, Dunavac, Sibnica, Butuš, Rogoznica, Buk, Belanoš and Sebeš, and large bogs of Reva, Veliko Blato (), Sebeš and Široka Bara. In the south, the area ends with a river island (ada) Kožara () and the southwest is occupied by the wetland of Beljarica.
After 1945, a dense system of canals was dug in the region. They mostly serve for the draining of the marsh, with almost all natural streams being adapted into the draining canals. In time, due to the lack of proper maintenance and their parallel function as the sewage, they became synonymous for pollution, being filled with waste and losing their function. As a result, the flooding of the settlements, especially Krnjača, Kotež and Borča, became regular occurrence during the rainy season. In total, there are of drainage canals, the largest density of agricultural canals in Europe. Of that, are canals in the urbanized zones and are specifically built for the agricultural production in the PKB Beograd company.
The defensive embankments on all sides of the region are long ("defense cassette"), as for six months a year, the waters of the surrounding rivers are higher than the land in Pančevački Rit. Some are embankments along the Danube (west and south), along the Tamiš (east) and along the Karaš (north).
