In Greek mythology, the name Leuconoe (/ljuːˈkɒnoʊi/; Ancient Greek: Λευκονόη, /leu̯konóɛː/) may refer to:

• Leuconoe, one of the Minyads,^[1] more commonly known as Leucippe.
• Leuconoe, daughter of Lucifer (Eosphorus) and mother of Philammon by Apollo.^[2] In some accounts, the mother of Philammon was called Chione^[3] or Philonis.^[4]
• In some editions of Hyginus' Fabulae, Leuconoe was the suggested reading for the name of the child of Poseidon and Themisto.^[5] The reading Leucon has been accepted as more appropriate.^[6]

In Roman literature, Leuconoe is a figure to whom Horace's Ode 11 of Book 1 of Odes is addressed.
