Dalj ( Hungarian: Dálya, Serbian Cyrillic: Даљ) is a village on the Danube in eastern Croatia, near the confluence of the Drava and Danube, on the border with Serbia. It is connected with the D519 highway and administratively located in the municipality of Erdut, Osijek-Baranja County.
During the Croatian War of Independence, the village became the site of the Dalj massacre—killing of 39 prisoners of war in August 1991. The prisoners were captured as Croatian policemen, Croatian National Guard troops and Civil defencemen and killed after the Yugoslav People's Army and Serbian paramilitaries captured Dalj on 1 August. Goran Hadžić, Croatian Serb political leader at the time, is charged with the war crime.
Hadžić is on trial at the International Criminal Tribunal for the former Yugoslavia (ICTY). The ICTY also charged Hadžić with illegal detention of hundreds of civilians in Dalj police station and a hangar near village's railway station. The detainees were beaten and otherwise physically abused.
