Marcus Gavius Maximus (died 156) was an eques of ancient Rome who held several imperial positions, both civil and military, under Hadrian and Antoninus Pius.
Firmum in northern Italy is considered his hometown, confirmed by the fact that his voting tribe, Palatina, is found there.
[7] Antoninus Pius later appointed him praetorian prefect, as the colleague of Marcus Petronius Mamertinus; this was one of the highest offices an eques could hold.
[10] This would confirm the Historia Augusta about this claim, and indicates that Maximus had the longest tenure as praetorian prefect of any man appointed to that office.
Civic munificence was virtually ubiquitous in the Roman world but we know of no particular connection that Gavius Maximus had with the port town.
