Baldwin IV of Jerusalem (1161–1185), known as the Leper King, was the king of Jerusalem, from 1174 until his death in 1185. He was admired by his contemporaries and later historians for his willpower and dedication to the Latin Kingdom in the face of debilitating leprosy. Choosing competent advisers, Baldwin ruled a thriving crusader state and succeeded in protecting it from the Muslim ruler Saladin.

The king or queen of Jerusalem was the supreme ruler of the Kingdom of Jerusalem, a Crusader state founded in Jerusalem by the Latin Catholic leaders of the First Crusade, when the city was conquered in 1099. Most of them were men, but there were also five queens regnant of Jerusalem, either reigning alone suo jure, or as co-rulers of husbands who reigned as kings of Jerusalem jure uxoris.
