Bosnian mujahideen (), also called El Mudžahid (from , mujāhid), were foreign Muslim volunteers who fought on the Bosniak (Bosnian Muslim) side during the 1992–95 Bosnian War. They first arrived in central Bosnia in the second half of 1992 with the aim of helping their Bosnian Muslim co-religionists in fights against Serb and Croat forces. Initially they mainly came from Arab countries, later from other Muslim-majority countries. Estimates of their numbers vary from 500 to 6,000. Bosnian War In the breakup of Yugoslavia in 1991, Slovenia and Croatia declared independence. War broke out in Croatia between the Croatian Army and the breakaway Serb Krajina. Meanwhile, the Bosnian Muslim leadership opted for independence. Serbs established autonomous provinces and Bosnian Croats took similar steps. The war broke out in April 1992. Muslim countries came to support the Bosnian Muslims and an independent Bosnia and Herzegovina. Support came from Iran, Pakistan, Saudi Arabia, Turkey, and other Muslim countries. There were also Islamist organizations and Muslim non-profit organizations and charitable trusts that supported the Bosnian Muslims. Muslim foreign fighters joined the Bosnian Muslim side. Volunteer mujahideen arrived from all around the world, including Afghanistan, Egypt, France, Indonesia, Iraq, Iran, Lebanon, Malaysia, Morocco, Pakistan, Russia (especially around Chechnya and Dagestan), Saudi Arabia, Spain, Thailand, Turkey, the United Kingdom, the United States and Yemen.

Foreign mujahideen arrived in central Bosnia in the second half of 1992 with the aim of fighting for Islam, helping their Bosnian Muslim co-religionists to defend themselves from the Serb and Croat forces. Some originally went as humanitarian workers, while some of them were considered criminals in their home countries for illegally travelling to Bosnia and becoming soldiers. On 13 August 1993, the Bosnian government officially organized foreign volunteers into the detachment known as El Mudžahid in order to impose control and order. Initially, the foreign mujahideen gave food and other basic necessities to the local Muslim population, who were deprived of such by the Serb forces. Once hostilities broke out between the Bosnian government and the Croat forces (HVO), the mujahideen also participated in battles against the HVO alongside ARBiH units. The foreign mujahideen recruited local young men, offering them military training, uniforms and weapons. As a result, some Bosniaks joined the foreign mujahideen and in the process became local mujahideen. They imitated the foreigners in both dress and behaviour,
