Aurelius Arpagius was a governor of one of the provinces of Roman Britain, probably Britannia Secunda. He is known from a single building inscription from a Roman fort at Birdoswald (RIB 1912), which describes the rebuilding of several buildings at the fort under the Tetrarchy. The inscription dates to the period AD 296-305, just after Rome had retaken Britain from Allectus.
