Robert Devreesse (28 May 1894, Cisai-Saint-Aubin – 1978) was a French priest and scriptor in the Vatican Library. His many works involve ground-breaking achievement in Greek (and also in Syriac) paleography, research into the life and work of Theodore of Mopsuestia and the history of the Patriarchate of Antioch in its early centuries. He was irregularly appointed curator of the Manuscripts department of the Bibliothèque Nationale and therefore fired in August 1944.
