Ostrovo (Serbian Cyrillic: Острово) is a village in the municipality of Kostolac, city of Požarevac, Serbia.

After abolishment of the frontier, in 1873, Ostrovo was included into Temes County of the Kingdom of Hungary and Austria-Hungary.

In 1942, Germans built an embankment that transformed island on which Ostrovo was located into an peninsula, connecting it with the southern bank of the Danube.

[2] Therefore, unlike the most of historical Serbian Banat, Ostrovo was included into Central Serbia and not into Autonomous Province of Vojvodina.

In 2002, population of Ostrovo numbered 685 inhabitants, including 583 Serbs, 95 people of unknown ethnicity, 3 Hungarians, 3 Macedonians, and 1 Montenegrin.
