Crito of Pieria is a shadowy historical figure. He is mentioned only in passing references, notably as a possible source for the 4th-century historian Ephorus. The ethnonym indicates an origin in Pieria, a region of northern Greece. The provided 5th-century BCE dating is inconsistent with the Hellenistic era label also supplied.

He is credited with a single, lost work: a Description of Sicily. No fragments or direct quotations survive.

His significance derives entirely from his use as a source. The Suda records that Ephorus consulted Crito’s work on Sicily, indicating it was considered a reputable geographical or historical account in antiquity.
