Hermaios King of Paropamisade from 90 BC to 70 BC.
Hermaeus Soter or Hermaios Soter (epithet means "the Saviour") was a Western Indo-Greek king of the Eucratid Dynasty, who ruled the territory of Paropamisade in the Hindu-Kush region, with his capital in Alexandria of the Caucasus (near today's Kabul, Afghanistan). Bopearachchi dates Hermaeus to c. 90–70 BCE and R. C. Senior to c. 95–80 BCE.

Hermaeus seems to have been successor of Philoxenus or Diomedes. Judging from his coins, Hermaeus' rule was long and prosperous, but came to an end when the Yuezhi, coming from neighbouring Bactria, overran most of his Greek kingdom in the Paropamisade around 70 BCE. According to Bopearachchi, these nomads were the Yuezhi, the ancestors of the Kushans, whereas Senior considers them Sakas.
