Innocent of Irkutsk was an Eastern Orthodox priest and missionary who served as the first bishop of Irkutsk. Born Ivan Kulczycki around 1680 in the Chernigov Governorate, he later became a monk at the Kiev Caves Lavra. After teaching at the Moscow Ecclesiastical Academy and serving in St. Petersburg, he was consecrated as the bishop of Pereyaslavl in 1721. Although intended for a mission to China, he was instead appointed to lead the see in Irkutsk in 1727, where he focused on local missionary work.
