Bogdan Žerajic (Serbian: ?????? ???????; 1 February 1886 – 15 June 1910) was a Bosnian Serb student of the Faculty of Law at the University of Zagreb.
In 1910 he attempted to assassinate General Marijan Varešanin, the Governor of Bosnia and Herzegovina, on the opening day of the Austro-Hungarian Parliament of Bosnia and Herzegovina, believing it to be illegal and illegitimate.
His attempt was his own initiative, an act of personal revolt against Austro-Hungarian annexation of Bosnia and Herzegovina.Žerajic was first among the young people of Bosnia and Herzegovina to pursue tyrannicide as a method of political struggle.
His act had great impact on young people in Bosnia and Herzegovina, while official press in Sarajevo and Belgrade generally referred to it as an act of a disturbed lunatic, which was also generally the view of an older generation of Sarajevo Serbs.
