The Astronomia (, "Astronomy") or Astrologia (, also "Astronomy") is a fragmentary Ancient Greek hexameter poem that was attributed to Hesiod during antiquity. As the title of the poem suggests, it was astronomical in focus, dealing with the stars. It has been suspected that the Astronomia influenced the style of Aratus' Phaenomena, but the remains of the Hesiodic poem found in ancient quotations are too meager to allow for certainty on this matter.
