Bacurius () was a Roman general of Georgian origin and a member of the royal family of Iberia (Kartli, eastern Georgia) mentioned by several Greco-Roman authors of the 4th and 5th centuries. It is accepted, but not universally, that all these refer to the same person, an Iberian "king" or "prince", who joined the Roman military ranks. Scholarly opinion is divided whether Bacurius can be identified with one of the kings named Bacurius the Great (), attested in medieval Georgian annals, who might have taken refuge in territories obtained by the Eastern Roman Empire during the Roman–Persian Wars that were fought over the Caucasus.
The oldest Georgian Bir el Qutt inscriptions mention Bacurius. He is also thought to be a possible maternal great-uncle or grandfather of Peter the Iberian.
Name
The name ' is the Latin form of the Greek Bakour (), itself a variant of the Middle Iranian Pakur, derived from Old Iranian bag-puhr ('son of a god'). The name "Bakur" is the Georgian (ბაკურ) and Armenian (Բակուր) attestation of Middle Iranian Pakur.
All contemporary sources are unequivocal in praising Bacurius's military skills and courage. Rufinus, whom Bacurius visited several times on the Mount of Olives and served him as a source of Christianization of Iberia, describes the general as a pious Christian, while the rhetorician Libanius, with whom Bacurius held correspondence, evidently regards him as a pagan and praises him both as a soldier and a man of culture.
