Elisæus of Albania was a patriarch and missionary credited as the primary illuminator of the Church of Caucasian Albania. Born in Jerusalem, he traveled to the region to spread the Christian faith. Historical traditions offer different accounts of his origins, variously describing him as a disciple of Saint Thaddeus or a direct follower of Jesus who was commissioned by James the Just. His efforts led to the establishment of early Christian foundations in the East, most notably in the area of Kish.
