In Greek mythology, Phoebe (/ˈfiːbi/ FEE-bee; Ancient Greek: Φοίβη, romanized: Phoíbē, associated with φοῖβος phoîbos, "shining") was the name or epithet of the following characters:

• Phoebe (Titaness), one of the Titans, grandmother of Apollo and Artemis.^[1]
• Phoebe (daughter of Leucippus), daughter of Leucippus.^[2]
• Phoebe, a hamadryad who became one of King Danaus's many wives or concubines and possible mother of some of these Danaïdes: Hippodamia, Rhodia, Cleopatra, Asteria, Glauce, Hippomedusa, Gorge, Iphimedusa and Rhode.^[3] Apollodorus only identified these daughters of Danaus by Phoebe and Atlantia (another hamadryad), not specifying who was the daughter of the other. These ten women joined the sons of Aegyptus who were begotten on an Arabian woman. Later on, these princesses slew their cousin-husbands during their wedding night.^[3] According to Hippostratus, Danaus had all of his progeny by a single woman, Europe, daughter of the river-god Nilus.^[4] In some accounts, he married his cousin Melia, daughter of Agenor, king of Tyre.^[5]
• Phoebe, one of the Heliades.^[6]
• Phoebe, a Spartan princess who was the daughter of King Tyndareus and Leda, daughter of King Thestius of Pleuron. She was the (half-)sister of Castor and Pollux, Helen, Clytemnestra, Timandra and Philonoe.^[7]
• Phoebe, one of the Amazons who fought against Heracles.^[8]
• Phoebe, an epithet of Artemis, also shared by Selene.

Also, Phoebe (crater) on Saturn's small moon Janus is named after Phoebe of Messenia.
