Trifun "Trifko" Grabež (; – 21 October 1916) was a Bosnian Serb member of the Black Hand organization which was involved in the assassination of Archduke Franz Ferdinand. Early life Trifko Grabež was born on in Pale, a small town in eastern Bosnia and Herzegovina. His father Đorđe Grabež was a Serbian Orthodox priest. At the age of seventeen, Grabež was expelled from school for striking one of his teachers. Grabež left home and moved to Belgrade, which was a part of the Kingdom of Serbia at the time. As well as continuing his education he joined the Black Hand secret society. For the next two years he spent most of his spare time with other nationalists who favoured a union between Bosnia and Herzegovina and Serbia.

However, his orders were not implemented and they managed to reach Bosnia and Herzegovina where they joined forces with fellow conspirators, Vaso and Veljko Čubrilović, Muhamed Mehmedbašić, Danilo Ilić and Cvijetko Popović.
