Heraios (Bactrian: Ηλου Ēlou, sometimes Heraus, Heraos, Miaos) was apparently a king or clan chief of the Kushans (reign: c. 1 –30 CE[citation needed]), one of the five constituent tribes of the Yuezhi, in Bactria, in the early 1st century CE.

[1] Several scholars question his existence as a separate historical figure and suggest that "Heraios" may have been another name for his nominal successor Kujula Kadphises.

[3] The coins bearing the name Heraios were silver and made in the Hellenistic style, using the Greek script.

The reverse shows the winged Greek goddess of victory Nike holding out a wreath, over Heraios mounted on a horse.

On some of the Heraios coins, his name has sometimes been read as ΗΛΟΥ or ΗΙΛΟΥ, which has been transliterated as "Ilou".
