Slobodan Praljak (Croatian pronunciation: [slobǒdan prǎːʎak]; 2 January 1945 – 29 November 2017) was a Bosnian Croat general found guilty by the International Criminal Tribunal for the former Yugoslavia (ICTY) of committing violations of the laws of war, crimes against humanity, and breaches of the Geneva Conventions during the 1992–1994 Croat–Bosniak War.

Praljak voluntarily joined the newly formed Croatian Armed Forces after the outbreak of the Croatian War of Independence in 1991. Before and after the war he was an engineer, a television and theatre director, and a businessman. Praljak was indicted by, and voluntarily surrendered to, the ICTY in 2004. In 2013, he was convicted for war crimes against the Bosniak population during the Croat–Bosniak War alongside five other Bosnian Croat officials, and was sentenced to 20 years in jail (minus the time he had already spent in detention). Upon hearing the guilty verdict upheld in November 2017, Praljak stated that he rejected the verdict of the court, and fatally poisoned himself in the courtroom.
