Autonomna Pokrajina Zapadna Bosna je bio mali, nepriznati entitet na sjeverozapadu Bosne i Hercegovine. Sastojala se od grada Velike Kladuše sa okolnim naseljima. Postojala je od 1993. do 1995. godine. Vođa pobune protiv vlade u Sarajevu bio je Fikret Abdić „Babo“. Autonomna Pokrajina Zapadna Bosna surađivala je sa Hrvatskom i Republikom Srpskom. Čak je firmi Agrokomerc iz Velike Kladuše u rječkoj luci odobrena bescarinska zona. A imali su i ugovor o slobodnoj trgovini sa Republikom Srpskom.  

      Područje Zapadne Bosne 1994. godine osvajaju snage Armije BiH, ali su nedugo zatim protjerane, uz obilnu pomoć vojske RS i RSK-a. Početkom 1995. Autonomna Pokrajina Zapadna Bosna je preimenovana u Republika Zapadna Bosna, no uskoro prestaje postojati jer je uništena zajedničkom vojnom akcijom Armije BiH i Hrvatske Vojske (u „Operaciji oluja“).

      The Autonomous Province of Western Bosnia (Autonomna Pokrajina Zapadna Bosna, Аутономна Покрајина Западна Босна) was a small unrecognized entity in the northwest of Bosnia and Herzegovina. It consisted of the town of Velika Kladuša and a few nearby villages, and existed between 1993 and 1995 as a result of secessionist politics by Fikret Abdić against the Bosnian central government during the Bosnian War.

      The Autonomous Province cooperated with Republic of Srpska as well as Croatia against Bosnian government. Fikret Abdić's role in undermining the Bosnian government was awarded by Croatian regime as well as those of Republic of Srpska. Agrokomerc was granted free-custom trade zone in the Croatian port of Rijeka, and free trade with territories controlled by Bosnian Serbs. The trade between Western Bosnia and Croatia was live during the Bosnian war.

      The territory of Western Bosnia was seized by the Bosnian government troops in 1994, but they were expelled later that year with the significant help of Serbs, and the Autonomous Province of Western Bosnia was re-established. In 1995 the province was renamed to Republic of Western Bosnia (Republika Zapadna Bosna, Република Западна Босна). It was soon militarily defeated during Operation Tigar and then wiped out completely during the joint Croatian and Bosnian government army action during the Operation Storm.
