Autocrates the Historian was a Hellenistic author of the 3rd–2nd century BCE. His existence is attested solely by a single citation in Athenaeus of Naucratis, who references his work on Thessaly. No biographical details survive.

His only known work is the Thessalica, a lost regional history of Thessaly. A single fragment from this text is preserved in Athenaeus’s Deipnosophistae.

Autocrates represents the prolific tradition of local historians in the Hellenistic period. His significance lies entirely in his status as a fragmentary author, providing a minor example of the vast body of lost regional historical literature from this era.
