Ceto (//; Ancient Greek: Κητώ, romanized: Kētṓ, lit. 'sea monster') is a primordial sea goddess in Greek mythology, the daughter of Pontus and his mother, Gaia. As a mythological figure, she is considered to be one of the most ancient deities, and bore a host of monstrous children fathered by Phorcys, another child of the Titans. The small solar system body 65489 Ceto was named after her, and its satellite after Phorcys.
Ceto was also variously called Crataeis (Κράταιις, Krataiis, from κραταιίς "mighty") and Trienus (Τρίενος, Trienos, from τρίενος "within three years"), and was occasionally conflated by scholars with the goddess Hecate (for whom Crataeis and Trienus are also epithets).
This goddess should not be confused with the minor Oceanid also named Ceto, or with various mythological beings referred to as ketos (plural kētē or ketea); this is a general term for "sea monster" in Ancient Greek.
In ancient texts
Hesiod's Theogony lists the children of Phorcys and Ceto as Echidna, the Gorgons (Euryale, Stheno, and the infamous Medusa), the Graeae (Deino, Enyo, Pemphredo, and sometimes Perso), and Ladon, also called the Drakon Hesperios ("Hesperian Dragon", or dragon of the Hesperides). These children tend to be consistent across sources, though Ladon is sometimes cited as a child of Echidna by Typhon and therefore Phorcys and Ceto's grandson.
Pliny the Elder mentions worship of "storied Ceto" at Joppa (now Jaffa), in a single reference, immediately after his mention of Andromeda, whom Perseus rescued from a sea-monster. S. Safrai and M. Stern suggest the possibility that someone at Joppa established a cult of the monster under the name Ceto. As an alternative explanation, they posit that Pliny or his source misread the name cetus—or that of the Syrian goddess Derceto.

- There are two major conflicting stories for Aphrodite's origins: Hesiod (Theogony) claims that she was "born" from the foam of the sea after Cronus castrated Uranus, thus making her Uranus' daughter; but Homer (Iliad, book V) has Aphrodite as daughter of Zeus and Dione. According to Plato (Symposium 180e), the two were entirely separate entities: Aphrodite Ourania and Aphrodite Pandemos.
- Homer, Odyssey, 1.70–73, names Thoosa as a daughter of Phorcys, without specifying a mother.
- Most sources describe Medusa as the daughter of Phorcys and Ceto, though the author Hyginus (Fabulae Preface) makes Medusa the daughter of Gorgon and Ceto.
