The Bosut (Serbian Cyrillic: Босут) is a river in the Syrmia region of eastern Croatia and northwestern Serbia. It is a 186 km long, slow and meandering left tributary of the Sava river.^[2]

The riverbed begins near the left embankment of the Sava river between Županja and Štitar (45°05′46″N 18°40′36″E / 45.09611°N 18.67667°E / 45.09611; 18.67667),^[3] which in the past^[4][5] was an outflow channel, and a connection with the Sava. Some 2,400 m (1.5 mi) farther, the Bosut gets its first water from the Berava river (45°06′59″N 18°40′45″E / 45.11639°N 18.67917°E / 45.11639; 18.67917). The narrow riverbed widens in Cerna, where it receives the water of the Biđ.^[6][3]

The river continues north toward the city of Vinkovci, the only major city on its course, and then turns southeast. Near Lipovac it receives its major tributary Spačva, and then enters Serbia near Batrovci. In its lower course, Bosut flows through a forested area in the Spačva region.

The river is known for its abundance of fish.^[7] It is thought that its name derives from the Indo-European root *bhogj, meaning "to flow". The same root is seen in hydronym "Bosna".^[8]
