Nedeljko Čabrinović (1895 - January 23, 1916) was a member of the Black Hand society, and one of seven assassins who made a successful attempt on the life of Franz Ferdinand, Archduke of Austria.

Born in Sarajevo, Čabrinović spent many of his post-school years as a handyman, before moving to Belgrade and working in a print shop, becoming familiar with anarchist literature.

In 1912 he joined the Black Hand, and two years later Dragutin Dimitrijevic, leader of the Black Hand, ordered Čabrinović, Gavrilo Princip and five other conspirators to assassinate Ferdinand, giving them each a gun and two bombs, along with a vial of cyanide (though it has been suggested that the cyanide was either old and ineffective, or that the Black Hand's supplier had deceived them and sold them a different, much weaker poison), telling them to swallow it if they were in danger of being caught.
