Joscelin I (died 1131) was a Frankish nobleman of the House of Courtenay who ruled as the lord of Turbessel, prince of Galilee (1112–1119) and count of Edessa (1118–1131). The County of Edessa reached its zenith during his rule. Captured twice, Joscelin continued to expand his county, even participating in the Battle of Azaz in 1125. Gravely injured during the collapse of a sapper mine, Joscelin marched his army to relieve the besieged fortress of Kaysun, and died soon after.
