Marcus(?) Aurelius Heraclianus (died 268) was a Roman soldier who rose to the rank of Praetorian Prefect in the latter part of the reign of the Emperor Gallienus. He was a member of the cabal of senior commanders of the Imperial field army that plotted and achieved the assassination of the Emperor Gallienus. His subsequent fate is uncertain. The only ancient reference has him committing suicide, but the circumstances are unclear.
