Ljubija (Serbian Cyrillic: Љубија) is a small town in Bosnia and Herzegovina.

It is located in the Bosanska Krajina region in the northwestern part of the country.

In the 19th century, Ljubija developed into one of the most important locations for the area's economy due to its iron ore deposits.

On 24–25 July 1992, the Fifth Kozara Brigade and Sixth Krajina Brigade of the Army of Republika Srpska and local Serb paramilitaries, totaling at 3,000, attacked Ljubija and killed 73 Bosnian Croat civilians.
