The Odyssey is one of two major ancient Greek epic poems attributed to Homer. It is one of the oldest extant works of literature still widely read by modern audiences. As with the Iliad, the poem is divided into 24 books. It follows the Greek hero Odysseus, king of Ithaca, and his journey home after the Trojan War. After the war itself, which lasted ten years, his journey lasted for ten additional years, during which time he encountered many perils and all his crewmate were killed. In his absence, Odysseus was assumed dead, and his wife Penelope and son Telemachus had to contend with a group of unruly suitors who were competing for Penelope's hand in marriage.

The Odyssey was originally composed in Homeric Greek in around the 8th or 7th century BCE and, by the mid-6th century BCE, had become part of the Greek literary canon. In antiquity, Homer's authorship of the poem was not questioned, but contemporary scholarship predominantly assumes that the Iliad and the Odyssey were composed independently, and the stories themselves formed as part of a long oral tradition.

Scholars still reflect on the narrative significance of certain groups in the poem, such as women and slaves, who have a more prominent role in the epic than in many other works of ancient literature. This focus is especially remarkable when considered beside the Iliad, which centers the exploits of soldiers and kings during the Trojan War.

The Odyssey is regarded as one of the most significant works of the Western canon. The first English translation of the Odyssey was in the 16th century. Adaptations and re-imaginings continue to be produced across a wide variety of mediums. In 2018, when BBC Culture polled experts around the world to find literature's most enduring narrative, the Odyssey topped the list. Here is the great tale as an exciting extended Icon Audiobook!
