In Greek mythology, Astris (Ancient Greek: Ἀστρὶς) or Asteria[1] was, in Nonnus's Dionysiaca,[2] one of the Heliades, daughters of Helios, either by the Oceanid Clymene[3] or the Oceanid Ceto.[4] She married the river god Hydaspes (the modern Jhelum River) and became mother of Deriades, king of the Indians.[5]
