The Krbava field and Udbina itself was the location of a medieval bishopric and the Battle of Krbava field of 9 September 1493, where the Croats under ban Emerik Derenčin (Hungarian: Imre Derencsényi) and the Frankopans suffered one of the major defeats at the hands of the Ottoman Empire. Udbina was managed by Ottomans between 1527-1689 (nominally to 1699) and included to the Sanjak of Lika in the Eyalet of Bosnia.
During World War II, Udbina was part of the Independent State of Croatia. The Orthodox Church of St. Nicholas (filial of the Church of the Holy Transfiguration of Mutilić) was destroyed during World War II and many local serbs were killed by Ustaše. St Nicholas Roman Catholic church was destroyed in 1947.
Before and after World War II, Serbs comprised Udbina's majority, as confirmed by 1931  and 1961–91 censuses, with smaller numbers of Croats and Muslims. In Yugoslavia, Udbina had a football club named "Krbava". The settlement of Udbina was part of the Korenica municipality. Udbina was under control of the Republic of Serbian Krajina during the Croatian War of Independence (1991–95). The local airport was used as airbase for offensive operations against Croatia and Bosnia, in direct defiance of NATO's Operation Deny Flight. The airstrip was eventually disabled by a 39 aircraft-strong strike on 21 November 1994. It was captured by Croatian forces during the Operation Storm on 7 August 1995 when most of Serbs living in Udbina escaped from invading forces.
