Operation Spider (Serbian: Операција Паук, Operacija Pauk) was a combined effort by Republika Srpska and the Republic of Serb Krajina to recover the territory of the Autonomous Province of Western Bosnia, which was a key ally of the Serbs. The Bosnian central government had previously overrun and seized the territory. The operation ended in a Serb victory and the Autonomous Province of Western Bosnia remained in existence until the fall of its key ally the Republic of Serbian Krajina and the subsequent end of the war.
