Medb is queen of Connacht in the Ulster Cycle of Irish mythology. Her husband in the core stories of the cycle is Ailill mac Máta, although she had several husbands before him who were also kings of Connacht. She rules from Cruachan (now Rathcroghan, County Roscommon). She is the enemy (and former wife) of Conchobar mac Nessa, king of Ulster, and is best known for starting the Táin Bó Cúailnge ("The Cattle Raid of Cooley") to steal Ulster's prize stud bull Donn Cúailnge.

Medb is strong-willed, ambitious, cunning and promiscuous, and is an archetypal warrior queen. She is believed by some to be a manifestation of the sovereignty goddess. Medb of Connacht is probably identical with Medb Lethderg, the sovereignty goddess of Tara.

She is described as a fair haired wolf queen, whose form was so beautiful that it robbed men of two-thirds of their valor upon seeing her.

How Medb came to power in Connacht and married Ailill mac Máta is told in the tale Cath Bóinde ("The Battle of the Boyne"), also known as Ferchuitred Medba ("Medb's man-share"). Her father, Eochaid Feidlech, the High King of Ireland, married her to Conchobar mac Nessa, king of Ulster, because he had killed Conchobar's purported father, the former High King Fachtna Fáthach, in battle. They had a son, Glaisne, but the marriage was a bad one and she left him. Eochaid gave Conchobar another of his daughters, Eithne (or Clothru), but Medb murdered her while she was pregnant; her son Furbaide was born by posthumous caesarian section.

Eochaid deposed the then-king of Connacht, Tinni mac Conri, and installed Medb in his place. However, Tinni regained a share of the throne when he and Medb later became lovers. Conchobar raped Medb after an assembly at Tara, and war ensued between the High King and Ulster. Tinni challenged Conchobar to single combat, and lost. Eochaid Dála of the Fir Domnann, who had been Tinni's rival for the kingship, protected the Connacht army as it retreated, and became Medb's next husband and king of Connacht. Medb demanded her husband satisfy her three criteria—that he be without fear, meanness, or jealousy. The last was particularly important, as she had many lovers. While married to Eochaid Dála, she took Ailill mac Máta, chief of her bodyguard, as her lover. Eochaid discovered the affair, challenged Ailill to single combat, and lost. Ailill then married Medb and became king of Connacht.

Medb and Ailill had seven sons, all called Maine. They originally all had other names, but when Medb asked a druid which of her sons would kill Conchobar, he replied, "Maine". She did not have a son called Maine, so she renamed all her sons as follows:

* Fedlimid became Maine Athramail ("like his father")
* Cairbre became Maine Máthramail ("like his mother")
* Eochaid became Maine Andoe ("the swift") and was also known as Cich-Maine Andoe or Cichmuine
* Fergus became Maine Taí ("the silent")
* Cet became Maine Mórgor ("of great duty")
* Sin became Maine Mílscothach ("honey-speech")
* Dáire became Maine Móepirt ("beyond description")

The prophecy was fulfilled when Maine Andoe went on to kill Conchobar, son of Arthur, son of Bruide – not Conchobar, son of Fachtna Fathach, as Medb had assumed the druid meant.

Medb and Ailill also had a daughter Findabair and another daughter called Cainnear or Cainnear Dearg (Red Cainnear) who was killed violently with a spear in the Tain Bo Flidais.

Out of jealousy for his affair with Medb, Ailill had Fergus killed. In his old age, after Conchobar's death, the Ulster hero Conall Cernach came to stay with Ailill and Medb, as they were the only household capable of supporting him. Medb tasked him to keep an eye on Ailill, who was seeing other women. Finding Ailill in flagrante, she ordered Conall to kill him, which he was happy to do in revenge for Fergus. However, the dying Ailill sent his men after him, and he was killed while trying to escape.

In her later years, Medb often went to bathe in a pool on Inchcleraun (Inis Cloithreann), an island on Lough Ree, near Knockcroghery. Furbaide sought revenge for the death of his mother. He took a rope and measured the distance between the pool and the shore, and practised with his sling until he could hit an apple on top of a stake Medb's height from that distance. The next time he saw Medb bathing he put his practice to good use and killed her with a piece of cheese. She was succeeded to the throne of Connacht by her son Maine Athramail.

According to legend, Medb is buried in Miosgán Médhbh, a 40-foot (12 m) high stone cairn on the summit of Knocknarea (Cnoc na Ré in Irish) in County Sligo. Supposedly, she is buried upright facing her enemies in Ulster. Her home in Rathcroghan, County Roscommon is also a potential burial site, with a long low slab named 'Misgaun Medb' being given as the most likely location.
