Xenion the Historian was a 4th-century BCE Greek historian. No biographical details survive. He is known only through fragments and references in later authors, primarily the geographer Strabo.
His sole attested work is the Cretika, a history of Crete. The work is lost and survives only in fragments quoted by Strabo.
Xenion is a source for Cretan history and myth. Strabo cites him as an authority but criticizes his accounts for including mythical and improbable elements. Xenion represents the fragmentary tradition of Hellenistic local chronicles, used and evaluated by later comprehensive authors.
