Hippostratus (Ancient Greek: Ἱππόστρατος, romanized: Hippostratos, meaning "army of horses") was an Indo-Greek king who ruled central and north-western Punjab and Pushkalavati.
Just like Apollodotus II, Hippostratus calls himself Soter, "Saviour", on all his coins, and on some coins he also assumes the title Basileos Megas, "Great King", which he inherited from Apollodotus II.
This may support Senior's scenario that Hippostratus extended his kingdom after Apollodotus' death.
Hippostratos did not, however, use the symbol of standing Athena Alkidemos, which was common to all other kings thought to be related to Apollodotus II.
Hippostratus issued silver coins with a diademed portrait on the obverse, and three reverses.
