Deirdre (Irish: Deirdre an Bhróin) is a tragic heroine in the Ulster Cycle of Irish mythology. She is also known by the title "Deirdre of the Sorrows."

Deirdre is an important character in Irish legend. In 2004, American scholar James MacKillop noted that she was the most well-known figure from Irish mythology in modern times.

In legend

Deirdre was the daughter of Fedlimid mac Daill, the royal storyteller. Before she was born, Cathbad, the chief druid at the court of Conchobar mac Nessa, king of Ulster, predicted that Fedlimid’s daughter would grow up to be very beautiful. However, the prophecy also warned that kings and lords would fight over her, much blood would be spilled because of her, and Ulster’s three greatest warriors would be forced into exile for her sake.

Many people told Fedlimid to kill the baby at birth, but Conchobar, who was excited by the description of her future beauty, decided to keep the child. He took Deirdre from her family and had her raised in seclusion by Leabharcham, a poet and wise woman. Conchobar planned to marry Deirdre when she was old enough.

As a young girl, Deirdre lived alone in the woodlands. One snowy day, she told Leabharcham that she would love a man with the colors she saw when a raven landed in the snow with its prey: hair as black as the raven, skin as white as snow, and cheeks as red as blood.

Leabharcham told Deirdre she was describing Naoise mac Uisneach, a handsome young warrior, hunter, and singer at Conchobar’s court. With Leabharcham’s help, Deirdre met Naoise, and they fell in love. Naoise and his brothers, Ardan and Ainnle, fled to Scotland with Deirdre. They lived happily there, hunting and fishing in beautiful places, including Loch Etive. Some versions of the story say Deirdre and Naoise had a son named Gaiar and a daughter named Aebgreine, who were raised by Manannan Mac Lir.

Angry and ashamed, Conchobar tracked them down. He sent Fergus mac Róich to invite them to return, promising safe passage. On the way back to Emain Macha, Conchobar forced Fergus to accept an invitation to a feast, which Fergus could not refuse because of a personal obligation called a geis.

Fergus sent Deirdre and the sons of Uisneach to Emain Macha with his son for protection. When they arrived, Conchobar sent Leabharcham to check if Deirdre had lost her beauty. To protect her, Leabharcham lied and told the king she was now old and unattractive. Conchobar then sent another spy, Gelbann, who saw Deirdre but was spotted by Naoise. Naoise threw a gold chess piece at Gelbann, blinding him.

Gelbann returned to Conchobar and said Deirdre was still beautiful. Conchobar then attacked the Red Branch house where Deirdre and the sons of Uisneach were staying. Naoise and his brothers fought bravely, helped by some Red Branch warriors, but Conchobar forced them to swear loyalty to him and had Deirdre taken from them. Éogan mac Durthacht threw a spear that killed Naoise, and his brothers were killed shortly after.

Fergus and his men arrived after the battle. Fergus was angry about the betrayal and went into exile in Connacht. Later, he fought against Ulster for Ailill and Medb in the war of the Táin Bó Cúailnge, sometimes called "the Irish Iliad."

After Naoise’s death, Conchobar married Deirdre. A year later, angry at her coldness, he asked her who she hated most besides himself. She answered, "Éogan mac Durthacht," the man who killed Naoise. Conchobar said he would give her to Éogan. As she was taken to him, Conchobar insulted her, saying she looked like a sheep between two rams. Hearing this, Deirdre threw herself from the chariot and died when her head hit a rock.
