The Siege of Bihać (Croatian: Opsada Bihaća) was the besieging and capture of the city of Bihać, Kingdom of Croatia within Habsburg Monarchy, by the Ottoman Empire in June 1592. With the arrival of Telli Hasan Pasha as the Beylerbey of the Bosnia Eyalet in 1591, a period of peace established between Emperor Rudolf II and Sultan Murad III ended and the provincial Ottoman armies launched an offensive on Croatia. Bihać, a nearly isolated city on the Una River that repelled an Ottoman attack in 1585, was one of the first targets.
