Saint Dionysius I (Russian: Дионисий); secular name: David (1300? – October 15, 1385) was a Russian Orthodox metropolitan in 1384–1385. A native of the Duchy of Kiev as a young man David entered the Kyiv Caves Lavra, where he was tonsured a hieromonk and given the religious name Dionysius. He is known to have spent a number of years living in a cave that he dug out himself on the banks of the Volga River not far from Nizhny Novgorod. Later, Dionysius founded the Pechersky Monastery on that same spot, which was dedicated in honour of the Ascension of the Lord. In 1374, he was consecrated the Bishop of Suzdal and won love and respect on the part of the locals.
