The Odyssey (/ˈɒdəsi/; Greek: Ὀδύσσεια, Odýsseia) is one of two major ancient Greek epic poems attributed to Homer. It is, in part, a sequel to the Iliad, the other work ascribed to Homer. The poem is fundamental to the modern Western canon, and is the second oldest extant work of Western literature, the Iliad being the oldest. Scholars believe it was composed near the end of the 8th century BC, somewhere in Ionia, the Greek coastal region of Anatolia.

The poem mainly centers on the Greek hero Odysseus (known as Ulysses in Roman myths) and his journey home after the fall of Troy. It takes Odysseus ten years to reach Ithaca after the ten-year Trojan War. In his absence, it is assumed he has died, and his wife Penelope and son Telemachus must deal with a group of unruly suitors, the Mnesteres (Greek: Μνηστῆρες) or Proci, who compete for Penelope's hand in marriage.
