Drogo (born c. 730) was a Frankish nobleman of the Pippinid family and the eldest son of Carloman, mayor of the palace of Austrasia under the Merovingian king Childeric III. He succeeded to his father's office in 747 but was soon squeezed out of power by his uncle, Pippin III, the mayor in Neustria. He resisted his uncle's takeover, but in 753 was captured and forced to become a monk.
