Capito (Καπίτων) was an Alexandrian grammarian who lived during the reign of the Roman emperor Tiberius (14–37 CE) [1]. He is sometimes identified as Gaius Ateius Capito, though this may conflate him with a Roman jurist [1]. Beyond his profession and era, no further biographical details are recorded.

The Byzantine encyclopedia Suda attributes to him a single, now lost, work titled On Sicily and the Cities Therein (Περὶ Σικελίας καὶ τῶν ἐν αὐτῇ πόλεων) [1]. The same source notes he wrote unspecified "other works," but no fragments survive [1].

His significance rests on his attestation as a lost author within the Hellenistic tradition of local history and geography. As a grammarian from Alexandria, he exemplifies the continuation of Greek scholarly activity under Roman rule, though the complete loss of his work precludes assessment of his specific contributions.
