Antony of Siya was a 16th-century Russian Orthodox monk and iconographer who established a significant monastic community in the Russian North. Born a peasant in 1478, he married in his early adulthood before entering a monastery in Kargopol following the death of his wife. After spending time wandering the shores of the Arctic Ocean, he founded the Antonievo-Siysky Monastery in 1520 on the Siya River. He operated under the jurisdiction of the archbishop of Novgorod and held land granted by Vasily III.
