Plato Epiphanes (Ancient Greek: , Plátōn ho Epiphanḗs, "Plato the God-Manifest") was a Greco-Bactrian king who reigned for a short time in southern Bactria or the Paropamisadae during the mid 2nd century BC.

Coinage The style of Plato's coins suggests that he was a relative — most likely a brother since Plato is a middle-aged man on his coins — of Eucratides the Great, whose rise to power is dated to around 170–165 BC.

Some of Plato's coins have inscriptions which may possibly be interpreted as dates using the Indo-Greek era which started around 186 BC. In that case Plato ruled around 140 BC. This matches the dating given by numismatician Bopearachchi, who places Plato between 145–140 BC, since his coins are not found in the ruins of Ai Khanoum, a Bactrian city which was destroyed during the reign of Eucratides.
