Kozara National Park (Serbian Cyrillic: Национални парк Козара) is a national park 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 Bosnia and Herzegovina. These 33.75 square kilometers of dense forest and hilly meadows have earned the nickname 'Green Beauty of Krajina'.
