Irish mythology is the collection of indigenous myths from the island of Ireland. These stories were originally passed down through oral tradition during the prehistoric era. In the early medieval period, Christian scribes began writing these myths down. These scribes often revised the stories to align with Christian learning and history. Despite these changes, Irish mythology remains the best-preserved branch of Celtic mythology.

Scholars conventionally group these myths into several distinct cycles. The Mythological Cycle contains tales about the Tuatha Dé Danann. This group is based on Ireland's pagan deities. This cycle also includes other mythical races like the Fomorians. Important works include the Lebor Gabála Érenn, also known as the Book of Invasions. This text serves as a legendary history of Ireland. Other notable works are the Cath Maige Tuired and the Aided Chlainne Lir.

The Tuatha Dé Danann are the primary supernatural beings in these myths. Their name is often interpreted as the folk of the goddess Danann or Ana. Some scholars believe Danann is a variant of the goddess Ana or Anu. These beings inhabit the Otherworld. This realm is described as a parallel world, a heavenly land beyond the sea, or a place under the earth. They can use a magic mist called a féth fíada to hide from humans.

Many prominent deities belong to the Tuatha Dé Danann. The Dagda is known as the great god. Lugh is described as long-armed, and Nuada is the silver-armed king. Other figures include the sea god Manannán and the healer Dian Cécht. There are also specialized gods like Goibniu the smith and Ogma the god of eloquence. Warrior goddesses often appear as a triad: The Morrígan, Macha, and Badb. The Morrígan is known to transform into a crow, an eel, a wolf, or a cow.

The Fomorians are a supernatural race often portrayed as hostile or monstrous. They were originally said to come from under the sea or the earth. Later stories depicted them as giants or sea raiders. They acted as the primary enemies of the Tuatha Dé Danann. However, the two races sometimes intermarried. A major conflict occurred during the Second Battle of Mag Tuired. In this battle, Lugh led a victory by slaying the Fomorian champion, Balor.

Heroic legends are divided into the Ulster Cycle and the Fenian Cycle. The Ulster Cycle focuses on the Ulaid people. Its most famous epic is the Táin Bó Cúailnge, or the Cattle Raid of Cooley.

The Fenian Cycle follows the hero Finn and his warrior band, the Fianna. Some scholars categorize these two groups differently. Ulster heroes are seen as tribal heroes functioning inside the community. In contrast, the Fianna are viewed as extra-tribal outsiders. They lived in the wilderness and often existed in a liminal state between the material world and the Otherworld.

The Fianna were not mere outcasts, but lived in voluntary exile. They spent summers in the wild training adolescents. This period of life served as a transition from puberty to manhood. Manhood was often identified with owning or inheriting property. The Fianna protected the community from other outsiders. Some historical sources even referred to them as "sons of death." This group shows how ancient Irish society managed different social roles and boundaries.

Much of our knowledge comes from medieval manuscripts. Key sources include the Book of the Dun Cow and the Book of Leinster. The Yellow Book of Lecan also contains important legends of Finn Mac Cumhaill. These documents were often compiled by Christian monks. These monks sometimes practiced euhemerism, which is the process of treating gods as if they were historical humans. These texts preserve a vast array of lore, from the sea-serpent Oilliphéist to the many lives of the Cailleach.
