Bosanska Otoka is a village on the river Una in Bosnia and Herzegovina. It is part of the Bosanska Otoka municipality of Una-Sana Canton, in the Federation of Bosnia and Herzegovina.

It was once known as Otok, the local word for island. Before the Bosnian War, the entire town was part of the Bosanska Otoka municipality, but after the Dayton Peace Agreement one part of the inhabited area of Otoka became a part of municipality Otoka na Uni, divided by the Inter-Entity Boundary Line. It lies on the ancient Roman road connecting the Podunavlje region to the Adriatic Sea

Otoka is located 11 km north of Bosanska Krupa, 23 km from Bužim and 22 km southwest of Novi Grad (formerly Bosanski Novi). Otoka spans both banks of the River Una and includes 24 river islets. The right and left banks are connected by a steel bridge built in 1920.
