Kozara National Park (Bosnian: Nacionalni park Kozara, Serbian Cyrillic: Национални парк Козара) is a national park in Bosnia and Herzegovina, that was proclaimed a protected national forest in 1967 by Josip Broz Tito. It is situated between the rivers Una, Sava, Sana and Vrbas, in the Republika Srpska entity of BiH. These 33.75 square kilometers of dense forest and hilly meadows have earned the nickname 'Green Beauty of Krajina'.
