Pyrgion the Historian was a Greek author, likely active during the Hellenistic or Imperial period. No biographical details survive. He is known only through citations by later writers, with his epithet identifying him as a historian.

His sole attested work is On the Festivals of Rhodes, a lost antiquarian treatise. It is cited by Athenaeus in his Deipnosophistae for a detail concerning fish and is listed in the 10th-century Byzantine encyclopedia, the Suda. The work focused on the religious customs and festivals of the island of Rhodes.

Pyrgion represents the practice of writing specialized local histories. His work is a rare example detailing the religious calendar of a major island state, providing valuable, though now fragmentary, insight into Rhodian cultural history. He is classified among the minor Greek historians.
