Nusreta Sivac (b. 1951 in Prijedor, Bosnia and Herzegovina) is a Bosnian activist for victims of rape and other war crimes. After studying law, she worked as a judge from 1978 until the outbreak of the Bosnian War in 1992. During the Bosnian War, she was detained in the Omarska concentration camp, where members of the Bosnian Serb Army tortured, abused, raped and killed prisoners. After the camp was closed in August 1992 due to press coverage and after fleeing to Croatia, Sivac became an activist for victims of rape and a member of the Women's Association of Bosnia and Herzegovina. In June 1995, along with other women, she helped prepare the first indictment of the International Criminal Tribunal for the former Yugoslavia (ICTY), which resulted in wartime rape being recognized as a war crime under international law. After returning to Prijedor in 1999, she continues her activism by attending conferences on peace and human rights and appearing in the media.
