Mitar Vasiljević (Serbian Cyrillic: Митар Васиљевић; 25 August 1954 – 5 November 2023) was a Bosnian Serb who was convicted of crimes against humanity and violation of the laws or customs of war by the International Criminal Tribunal for the Former Yugoslavia (ICTY) for his actions in the Višegrad region during the Bosnian War.
He was a member of Milan Lukić's White Eagles paramilitary group.
While he was originally scheduled to be tried along with Milan and Sredoje Lukić, his case proceeded on its own as the others were still at large at the time.
Vasiljević was found guilty on four charges and was sentenced to twenty years' imprisonment, which was reduced to fifteen years after an appeal.
On 12 March 2010, Vasiljević was granted early release.
