Hybla Gereatis (Greek: Ὕβλα ἡ Γελεᾶτις), was an ancient city of Sicily, located on the southern slope of Mount Etna, not far from the river , in the modern comune of Paternò. There were at least three (and possibly as many as five) cities named "Hybla" in ancient accounts of Sicily which are often confounded with each other, and which it is sometimes very difficult to distinguish. Hybla Gereatis has been described as the largest and most considerable of the Sicilian cities called Hybla, thence equated with Hybla Major or Magna.
