Amyntas Nicator (Ancient Greek: Ἀμύντας Νικάτωρ, romanized: Amýntas Nikátōr; epithet means "the Victorious") was an Indo-Greek king.

His coins have been found both in eastern Punjab and Afghanistan, indicating that he ruled a considerable territory.

Some of his coins feature the reverse of fighting Athena typical for Menander's descendants.

The epithet Nikator (Victor) was previously only used on the Bactrian coins of Agathocles, a century before Amyntas' reign.

His bronzes feature the syncretic deity Zeus-Mithra wearing a phrygian cap and Athena standing at rest, both forming the vitarka mudra.
