Azes I (Greek: Ἄζης Azēs, epigraphically ΑΖΟΥ Azou; Kharosthi: 𐨀𐨩 A-ya, Aya[1]) was an Indo-Scythian ruler who ruled around c. 48/47 BCE – 25 BCE[2] with a dynastic empire based in the Punjab and Indus Valley,[3] completed the domination of the Scythians in the northwestern Indian subcontinent.

Azes's name is attested on his coins in the Greek form Azēs (Ἄζης) and the Kharosthi form Aya (𐨀𐨩),[1] which are both derived from the Saka name *Aza, meaning "leader".

It was widely believed that the era was begun by Azes's successors by simply continuing the counting of his regnal years.
