Strato III Philopator (Greek: Στράτων Γ΄ Φιλοπάτωρ; epithet means "the Father-loving") was an Indo-Greek king who ruled c. 25 BCE to 10 CE.

He may have been supplanted, in conjunction with his father or later as an independent king, by the Indo-Scythian Northern Satraps, particularly Rajuvula and Bhadayasa, whose coins were often copied.

The decay was due to the increasing pressure of the Indo-Scythian nomads on the remaining Greek pockets, as well as their long isolation from the rest of the Hellenistic world.

On some of Strato II's silver drachms the letter sigma is written as C, a not uncommon trait on late Hellenistic coins in the east.

This is the case of the Northern Satraps, who ruled in the territories from Sagala in Eastern Punjab to Mathura, such as Rajuvula.
