Archimandrite Charalambos (Galanopoulos) of Dionysiou (or Haralambos Dionysiatis, Greek: Χαράλαμπος Διονυσιάτης; 1910 in Russia – 1 January 2001 in Dionysiou Monastery, Mount Athos) was a Greek Orthodox Christian monk who served as the abbot of Dionysiou Monastery from 1979 to 2000.^[1]

In 1910, he was born in southern Russia to Pontic Greek parents, namely Leonidas (Λεωνίδας) and Despina (Δέσποινα) Galanopoulos.^[2] He and his family moved to Arkadiko, Drama (Αρκαδικό της Δράμας) in 1922. He moved to the Little Saint Anne's Skete at Mount Athos in September 1950, where he became a disciple of Joseph the Hesychast.^[3] Later, he moved with Joseph the Hesychast and his disciples to New Skete. When Joseph the Hesychast died in 1959, he remained at New Skete until 1967.^[2][4] In 1967, Charalambos and his 12 disciples moved to Bourazeri, near Karyes. By 1979, Charalambos had 20 disciples, among whom was Elder Hilarion of New Skete.^[5]

In 1979, he was ordained as the abbot of Dionysiou Monastery, succeeding Archimandrite Gabriel of Dionysiou who had been Abbot of Dionysiou since 1936.^[5]
