Hippias of Erythrae was a Hellenistic historian of the 1st century BCE from the Ionian city of Erythrae in Asia Minor. No details of his personal life or education survive. He is identified solely by his ethnonym and his work on the history of his native city.

His only known work is the lost History of Erythrae, which survives in fragments. These citations indicate it treated the foundation myths and local history of the city. Hippias represents the genre of local historians who preserved civic traditions in the Hellenistic period.

His fragments were used by later authors like Strabo and Stephanus of Byzantium. They provide valuable evidence for the topography, cults, and historical memory of Erythrae.
