Hagana (, ) was an Indo-Scythian Northern Satrap (ruled in Mathura in the 1st century BCE, probably after 60 BCE).
Hagana's name is attested on his coins in the Brahmi form , which is derived from the Saka name , meaning "leader, chief".
In central India, the Indo-Scythians are thought to have conquered the area of Mathura over Indian kings around 60 BCE, thus founding the Northern Satraps. Some of their first satraps were Hagamasha and Hagana, who were in turn followed by Rajuvula, but according to some authors, Rajuvula may have been first.
