The gens Oclatinia was an obscure Roman family of imperial times.
It is best known from a single individual, Marcus Oclatinius Adventus, consul for the second time[i] in AD 218, together with the emperor Macrinus.
From various sources, we know that he was procurator Augustorum under Septimius Severus in AD 202,[1] and governor of Britain between 205 and 207.
[2][3][4] The nomen Oclatinius clearly shares a root with Oclatius, borne by Tiberius Oclatius Severus, consul suffectus in AD 160, and is perhaps an orthographic variant of Ocratius, part of a class of gentilicia formed using the suffix -atius, derived from place-names ending in -as or -atis, or passive participles ending in -atus.
