What is the name of Odysseus's mother, whom he meets in Hades?

The name of Odysseus’s mother, whom he meets in Hades, is Anticlea.

Odysseus encounters Anticlea during the underworld episode in Book 11 of the Odyssey. He initially keeps her away while waiting to speak with Tiresias, then lets her approach after receiving the prophet’s message. Anticlea asks why her living son has come among the dead, and Odysseus tells her about his troubled voyage home.

She explains that she died from grief and longing during his long absence. She also gives him news of Ithaca: Laertes is wasting away in sorrow, Penelope remains faithful but distressed, and Telemachus is managing the household. Odysseus tries three times to embrace her, but her shade is incorporeal and slips through his arms.

Anticlea is the daughter of Autolycus and the wife of Laertes. Homer presents Laertes as Odysseus’s father, although later traditions claim that Sisyphus fathered Odysseus before Anticlea married Laertes. That disputed genealogy does not change the answer to this question: in Homer’s Odyssey, Anticlea is the mother Odysseus meets in Hades.
