The Russian Orthodox Diocese of Sourozh (Russian: Суро́жская епа́рхия) is a diocese of the Russian Orthodox Church (ROC), covering the islands of Great Britain and Ireland. Since 28 December 2018, the Diocese of Sourozh is part of the Patriarchal Exarchate in Western Europe. The diocese's name is taken from an ancient see in the Crimea that no longer has a bishop. The patron saint of the diocese is St Stephen of Sourozh, an eighth-century Archbishop of Sourozh (today Sudak) and Confessor of the Faith during the Iconoclastic Controversy.
