Nedeljko Cabrinovic (Serbian Cyrillic: ??????? ??????????; 2 February 1895 – 20 January 1916) was a Bosnian Serb member of the pro-Yugoslav Young Bosnia movement and one of seven young men of a secret society known as the Black Hand who conspired to assassinate Archduke Franz Ferdinand during his June 1914 visit to Sarajevo.
All seven men were arrested; during the trial, Cabrinovic and other members stated that the assassination reflected their anarchist beliefs.
In response, Austria-Hungary issued a démarche to Serbia known as the July Ultimatum, leading to the outbreak of World War I.
