Nedeljko Čabrinović (Serbian Cyrillic: Недељко Чабриновић; 1 February 1895 – 23 January 1916) was one of the Young Bosnian conspirators who planned the assassination of Archduke Franz Ferdinand on 28 June 1914.

On the day of the assassination, Čabrinović threw a bomb that missed the car carrying the Archduke and his wife Sophie, Duchess of Hohenberg, exploding instead under the escort vehicle travelling behind.

Čabrinović started various apprenticeships, eventually entering the Serbian printing plant in Sarajevo where he learned typesetting for the next two years.

[3] Čabrinović returned to Sarajevo in 1912, finding work in another printing press he decided to join a strike against the order of his father.

[4] Čabrinović then went back to Belgrade but after his banishment was lifted with the help of friends and relatives, he returned to Sarajevo becoming in 1912 a full-time union member,[5] that same year he made the acquaintance of Gavrilo Princip.

[6] Čabrinović left Sarajevo in March 1913, finding work at a Slovene printing plant in Trieste[7] before returning to Belgrade in October 1913.

[10] Princip convinced Čabrinović and an old school friend Trifko Grabež, the 18-year-old son of a village priest, to join him in starting a plot to attack and kill the Archduke during his official visit to Sarajevo.

[12] Ciganović then approached Chetnik leader Major Vojislav Tankosić, another Black Hand member of Bosnian descent, from whom they obtained weapons and received training on how to use them.

[11] Čabrinović, Princip, and Grabež, equipped with five Browning pistols, six grenades, and pills of cyanide left Belgrade towards the end of May 1914.

[13] Archduke Franz Ferdinand of Austria and his wife, Duchess Sophie Chotek arrived in Sarajevo by train shortly before 10 a.m. on 28 June 1914.

Just before 10:30 am,[15] when the motorcade passed the central police station, Čabrinović standing on the river side of the boulevard, threw his M.12 Vasić hand grenade towards the car of the Archduke.
