Before the war in Bosnia the municipality of the same name had a bigger area surface. A larger part of the pre-war municipality is part of the Republika Srpska, including the city itself, (the Doboj Region). The southern rural areas are part of the Zenica-Doboj Canton of the Federation of Bosnia and Herzegovina, and the eastern rural part of the municipality is part of the Tuzla Canton, also in the Federation of Bosnia and Herzegovina. The parts of the pre-war Doboj Municipality that are in the Federation of Bosnia and Herzegovina are the municipalities of Doboj South (Doboj Jug) and Doboj East (Doboj Istok) and the Municipality of Usora. The northern suburbs of Doboj are extending into the peri-Pannonian plains, and effectively mark the southern tip of this great Central European plain. The southern (Doboj-South)and eastern suburbs (Doboj-East) are spread on the gentle hills which extend to larger Central Bosnian mountain areas (Mt. Ozren in south-east, Mt. Krnjin in the west)
