Humphrey IV of Toron (c. 1166 – 1198) was a leading baron in the Kingdom of Jerusalem. He inherited the Lordship of Toron from his grandfather, Humphrey II, in 1179. He was also heir to the Lordship of Oultrejourdan through his mother, Stephanie of Milly. In 1180, he renounced Toron on his engagement to Isabella, the half-sister of Baldwin IV of Jerusalem. The king, who had suffered from leprosy, allegedly wanted to prevent Humphrey from uniting two large fiefs. Humphrey married Isabella in Kerak Castle in autumn 1183. Saladin, the Ayyubbid sultan of Egypt and Syria, laid siege to Kerak during the wedding, but Baldwin IV and Raymond III of Tripoli relieved the fortress.
Baldwin IV made his young nephew, Baldwin V, his successor before his death, but Baldwin V also died in the summer of 1186. The barons, who did not want to acknowledge the right of Baldwin V's mother, Sybilla, and her husband, Guy of Lusignan, to inherit the kingdom, decided to proclaim Humphrey and his wife king and queen. However, Humphrey, who did not want to reign, deserted them and did homage to Sybilla and Guy. He was captured in 1187 at the Battle of Hattin, where Saladin imposed a crushing defeat on the united army of the Kingdom of Jerusalem. His mother offered the surrender of the fortresses of Oultrejordain to Saladin in exchange for Humphrey's release. Although the garrisons of Kerak and Montréal refused to surrender, Saladin set Humphrey free. Kerak only fell to Saladin's troops in late 1188, Montréal in early 1189.
After Queen Sybilla's death in the autumn of 1190, most barons of the realm (including Isabella's stepfather, Balian of Ibelin) wanted to give Isabella in marriage to Conrad of Montferrat, a successful military leader. The marriage of Humphrey and Isabella was annulled, although they protested the decision. Humphrey joined the retinue of King Richard I of England during his crusade in 1191–1192. Since Humphrey was fluent in Arabic, he conducted negotiations with Saladin's brother, Al-Adil, on Richard's behalf.
