In ancient Greek mythology and religion, Leto is a Titaness, daughter of Coeus and Phoebe, and the mother of Apollo and Artemis by Zeus. She is remembered above all for her difficult search for a birthplace — settled on the floating island of Delos — and for her later role as a mild kourotrophic goddess of motherhood, often worshipped with her twin children. Her Roman equivalent is Latona.

I.Family and character
Leto is the daughter of the Titans Coeus and Phoebe and sister of Asteria (mother of Hecate). By Zeus she bore Apollo and Artemis; early epic confirms the sibling pair, while Pindar and later authors present them as twins. Hesiod calls her always mild and kind among gods and mortals. Her Roman name Latona is a Latinization influenced by Etruscan Letun.
Kos and Hyperborea both claim associations with her birth or origins. Unlike most of Zeus's divine lovers, she is relentlessly persecuted by Hera in the pregnancy narratives — a treatment more typical of mortal rivals — which some scholars read as a sign that older mortal and divine strands may have fused in her figure.
II.Birth of Apollo and Artemis
In the Homeric Hymn to Apollo and later tellings, Hera forbids the earth to shelter the pregnant Leto. After wandering, Leto reaches Delos — a floating or formerly unfixed island, sometimes linked to her sister Asteria — and after prolonged labour gives birth, usually with Artemis born first and aiding her mother's delivery of Apollo. Variants place Artemis on Ortygia, delay Eileithyia's arrival for nine days, or have Poseidon conceal Delos under waves so that Hera's ban on terra firma does not apply.
Chthonic enemies pursue her: the Delphic serpent Python and the giant Tityos, both sometimes sent by Hera. Apollo and Artemis later avenge their mother by killing these assailants. Leto also appears among the gods at Troy in the Iliad and is shown fighting in Gigantomachy art (notably the Pergamon Altar).
III.Cult and later reception
Her principal Anatolian sanctuary, the Letoon near Xanthos, united Lycian city-states and treated her as a regional mother goddess; Greek inscriptions call her children the national gods of Lycia. On Delos she formed a triad with Apollo and Artemis and was represented by an archaic wooden image. Elsewhere she was usually honoured beside her children — at Argos, Delphi, Sparta, Mantinea, Crete (including Phaistos, where Leto Phytia is linked to the Ecdysia), and other sites. Herodotus identified an Egyptian cult at Buto with Leto via the goddess Wadjet.
Famous punitive myths include the Lycian peasants turned into frogs for denying her water and the destruction of Niobe's children after Niobe mocked Leto's lesser number of offspring. This entry concerns the Titaness mother of Apollo and Artemis — not the asteroid 68 Leto or the minor planet 639 Latona named after her.
