Sophagasenos also spelled Sophagasenus or Sophagasenas is a local Indian king ruling in Kabul and Kapisa valley (Paropamisade of the classical writings) during the last decade of 3rd century BC.

Sophagasnus finds reference only in "The Histories" of Polybius.

The identity of Sophagasenus is not clear.

Many historians believe that Sophagasenus was a princely scion of the Mauryas of Magadha but others believe him to have been a non-Mauryan local ruler from the area he ruled i.e.

from Kabul/Kapisa land.
