Bohemond IV of Antioch, also known as Bohemond the One-Eyed (French: Bohémond le Borgne; c. 1175–1233), was Count of Tripoli from 1187 to 1233, and Prince of Antioch from 1201 to 1216 and from 1219 to 1233. He was the younger son of Bohemond III of Antioch. The dying Raymond III of Tripoli offered his county to Bohemond's elder brother, Raymond, but their father sent Bohemond to Tripoli in late 1187. Saladin, the Ayyubid sultan of Egypt and Syria, conquered the County of Tripoli, save for the capital and two fortresses, in summer 1188. The county was included in the truce that Bohemond's father made with Saladin in 1192.

Bohemond's elder brother died in early 1197, leaving a posthumous son, Raymond-Roupen. Raymond-Roupen's mother, Alice, was the niece of Leo I of Cilicia who persuaded the Antiochene noblemen to acknowledge Raymond-Roupen's right to succeed his grandfather. However, the Latin and Greek burghers, who had formed a commune in 1194 to prevent Leo from seizing Antioch, proclaimed Bohemond heir to the principality in 1198. After his father died in April 1201, Bohemond seized Antioch with the support of the commune, the Knights Templar and Hospitallers, and the Italian merchants. He made an alliance with Az-Zahir Ghazi, the Ayyubid emir of Aleppo, and Kaykaus I, the Seljuq sultan of Rum, who often invaded Cilicia during the following years, to prevent Leo from attacking Antioch.
