The gens Oclatia was an obscure plebeian family at ancient Rome.
The only member known to have held any magistracy is Gaius Oclatius Modestus, quaestor in the first half of the second century, but many Oclatii are known from inscriptions.
The nomen Oclatius belongs to a class of gentilicia formed using the suffix -atius, based on place-named ending in -as or -atis, and passive participles ending in -atus.
It appears to share a common root with the nomen Oclatinius, and both might be an orthographic variant of Ocratius.
