Kostajnica, also known as Bosanska Kostajnica (Cyrillic script Босанска Костајница), is a town and municipality in northern Bosnia and Herzegovina. The town and municipality are situated in the north-western part of the Republika Srpska entity and northern part of the Bosanska Krajina region. The municipality was created from part of the pre-war municipality of Bosanski Novi. It is located across the Una from Hrvatska Kostajnica, Croatia.


During the Bosnian War, it was renamed to Srpska Kostajnica (Српска Костајница). After the war, High Representative for Bosnia and Herzegovina decreed that name is unconstitutional. After that, name of the town was changed to Kostajnica.[2]
