Scheria or Scherie (/ˈskɪəriə/; Ancient Greek: Σχερία or Σχερίη), also known as Phaeacia (/fiːˈeɪʃə/) or Faiakia, was a region in Greek mythology, first mentioned in Homer's Odyssey as the home of the Phaeacians and the last destination of Odysseus in his 10-year journey before returning home to Ithaca. It is one of the earliest descriptions of a utopia.

Before leaving Ogygia, Odysseus builds a raft and sails eastwards, instructed by Calypso to navigate using the stars as a celestial reference point. On the eighteenth day appear the shadowy mountains of the land of the Phaeacians, that looked like a shield in the misty deep. Poseidon spots his raft and seeking vengeance for his son Polyphemus who was blinded by Odysseus, produces a storm that torments Odysseus. After three days of struggle with the waves, he is finally washed up on Scheria.

Meanwhile, the goddess Athena sneaks into the palace, disguised as a sea-captain's daughter, and instructs princess Nausicaa (the daughter of King Alcinous) in her sleep to go to the seashore and wash her clothes. The next morning, Nausicaa and her maids go to the seashore, and after washing the clothes, start to play a game on the beach, with laughs, giggles and shouts. Odysseus, sleeping nearby exhausted from his adventure, is awakened by the shouts. He covers his nakedness with thick leaves and goes to ask for help from the group. Upon seeing the unkempt Odysseus in this state, the maids run away, but, Nausicaa, encouraged by Athena, stands her ground and talks to him. To excuse the maids, she admits that the Phaeacians are "the farthermost of men, and no other mortals are conversant with them", so they run away since they have never seen a stranger before. Nausicaa, being hospitable, provides clothes, food and drink to Odysseus, and then directs him to the palace of King Alcinous.

Following Nausicaa's instructions, Odysseus sought to enter the palace of King Alcinous and plead for mercy from the queen, Arete, so he could make his way home. On his way to the palace, Odysseus meets Athena disguised as a local girl. In her disguised state, Athena advises him about how to enter the palace. Athena, knowing that the Phaeacians were hostile towards men from the outlands, cloaked Odysseus in a mist that hid him from the Phaeacians' gaze. Under Athena's protection, Odysseus passes through all of the protection systems of the palace and enters the chamber of King Alcinous. Odysseus throws his arms around the queen's legs and supplicates her. Naturally, Alcinous and his court are surprised to see a stranger walking into their secured palace. It is only after Echeneus, a Phaeacian elder, urges King Alcinous to welcome the stranger that they offer Odysseus hospitality.

The front doors of the palace are flanked with two dogs made of silver and gold, constructed by Hephaestus. The walls of the palace are made of bronze that "shines like the sun", with gates made of gold. Within the walls, there is a magnificent garden with apple, pear, and pomegranate trees that grow year-round. The palace is even equipped with a lighting system consisting of golden statues of young men bearing torches. After Odysseus tells Alcinous and his court the story of his adventures after the Trojan War, the Phaeacians take him to Ithaca on one of their ships.

The Phaeacians possessed remarkable ships. They were quite different from the penteconters, the ships used during the Trojan War, and they were steered by thought. King Alcinous says that Phaeacians carried Rhadamanthus to Euboea, "which is the furthest of any place" and came back on the same day. He also explains to Odysseus what sort of information the Phaeacian ships require in order to take him home to Ithaca.

Tell me also your country, nation, and city, that our ships may shape their purpose accordingly and take you there. For the Phaeacians have no pilots; their vessels have no rudders as those of other nations have, but the ships themselves understand what it is that we are thinking about and want; they know all the cities and countries in the whole world, and can traverse the sea just as well even when it is covered with mist and cloud, so that there is no danger of being wrecked or coming to any harm.

Homer describes the Phaeacian ships as fast as a falcon and gives a vivid description of the ship's departure.
