The Derventa municipality borders Brod, Modriča, Doboj, Stanari, Prnjavor and Srbac, as well as Croatia across the Sava river.

The town of Derventa lies on the river Ukrina, and roads lead from it to Brod, Kotorsko (Doboj), Prnjavor (Banja Luka) and Srbac.

The town has a suburb called Derventski Lug, which has grown substantially in recent years due to the growth of the municipality.

The HVO eventually lost control of Derventa after Operacija Koridor '92 by the VRS and they were pushed up north, and as a result of the battle most of the Croats and Bosniaks were ethnically cleansed from the area, and Serb refugees from war-affected regions shortly settled in the town.
