Eochaid Mugmedón was a legendary Irish king. According to medieval Irish legend and historical tradition, Eochaid was a High King of Ireland, best known as the father of Niall of the Nine Hostages and ancestor of the Uí Néill and Connachta dynasties. He is not mentioned in the list of kings of Tara in the Baile Chuind, but is included in the synthetic lists of High Kings in the Lebor Gabála Érenn, the Irish annals, Geoffrey Keating's history, and the Laud Synchronisms.
Eochaid or Eochu Étgudach or Etgedach ("negligent"?), son of Daire Doimthech, son of Conghal, son of Eadaman, son of Mal, son of Lugaid, son of Íth, son of Breogán, was, according to medieval Irish legend and historical tradition, a High King of Ireland. According to the Lebor Gabála Érenn he was chosen as king by the remaining quarter of the men of Ireland after the other three-quarters had died with the former king, Tigernmas, while worshipping the deity Crom Cruach. He introduced a system whereby the number of colours a man could wear in his clothes depended on his social rank, from one colour for a slave to seven for a king or queen. He ruled for four years, until he was killed in battle at Tara by Cermna Finn, who succeeded to the throne jointly with his brother Sobairce. His reign is synchronised with that of Eupales in Assyria. The chronology of Geoffrey Keating's Foras Feasa ar Éirinn dates his reign to 1159–1155 BC, that of the Annals of the Four Masters to 1537–1533 BC.
Sobairce, son of Ebric and a great great grandson of Míl Espáine, was, according to medieval Irish legend and historical tradition, joint High King of Ireland with his brother Cermna Finn. The pair came to power after Cermna killed the previous incumbent, Eochaid Étgudach, in battle at Tara. They were the first High Kings to come from the Ulaid. They divided the country between them, the border running from Drogheda to Limerick. Sobairce ruled the northern half from Dún Sobairce, Cermna the southern half from Dún Cermna. They ruled for forty years. Sobairce died at the hands of Eochaid Menn, son of the king of the Fomorians. Cermna was killed in the same year by Eochaid Faebar Glas, son of the previous High King Conmáel, in the battle of Dún Cermna. The Lebor Gabála Érenn synchronises their reign with those of Laosthenes in Assyria and Rehoboam in Judah. The chronology of Geoffrey Keating's Foras Feasa ar Éirinn dates their reign to 1155–1115 BC, that of the Annals of the Four Masters to 1533–1493 BC.
Sírna Sáeglach, son of Dian mac Demal, son of Demal mac Rothechtaid, son of Rothechtaid mac Main, was, according to medieval Irish legend and historical tradition, a High King of Ireland. He separated the province of Ulster from the authority of the High King, and is said to have made war against the Ulaid, who had killed his great grandfather, for a hundred years according to the Lebor Gabála Érenn, 150 years according to the Annals of the Four Masters, but Geoffrey Keating, citing an ancient poem, gives him only twenty-one years. According to one version of the Lebor Gabála, the Ulaid united with the Fomorians and gave him battle at Móin Trógaide in County Meath, but a plague fell on them and the leaders of both sides died. According to another version, agreed by Keating and the Four Masters, Sírna was killed by Rothechtaid Rotha at Alind. The Lebor Gabála synchronises the start of his reign with the reign of Deioces of the Medes, and his death with his successor Phraortes. The chronology of Keating's Foras Feasa ar Éirinn dates his reign to 814–794 BC, that of the Annals of the Four Masters to 1181–1031 BC.
Sírlám, son of Finn mac Blatha, was, according to medieval Irish legend and historical tradition, a High King of Ireland. He took power after killing his predecessor, Lugaid Íardonn, in Ráth Clochair. His name means "long hand" or "long arm", and it is said his arms reached the ground when was standing up. He ruled for thirteen years according to the Lebor Gabála Érenn, or sixteen according to Geoffrey Keating and the Four Masters. He drove Lugaid's son Eochu Uairches into exile, but after twelve years overseas Eochu returned and killed him with an arrow. The Lebor Gabála synchronises his reign with that of Artaxerxes I of Persia. The chronology of Keating's Foras Feasa ar Éirinn dates his reign to 649–633 BC, that of the Annals of the Four Masters to 872–856 BC.

After Lugaid was overthrown and killed by Sírlám, Eochu was driven into exile overseas, but he returned after twelve years, killed Sírlám with an arrow, and took the throne. His epithet is obscure: the Lebor Gabála Érenn says he gained it because of his exile, while Geoffrey Keating explains it as meaning "bare canoes", because he had canoes for a fleet, in which he and his followers used to plunder neighbouring countries. He ruled for twelve years, before he was killed by Eochu Fíadmuine and Conaing Bececlach. The Lebor Gabála synchronises his reign with that of Artaxerxes I of Persia.

He ruled for seven years, after which Conaing killed him and became High King of the whole island. The Lebor Gabála synchronises Lugaid's reign with those of Artaxerxes I and Darius II (423–404) of Persia. The chronology of Keating's Foras Feasa ar Éirinn dates his career to 616–609 BC, that of the Annals of the Four Masters to 839–832 BC.

Finally he and Eochu Fíadmuine's son Lugaid Laigdech killed Airgetmar, and Dui took the throne himself, ruling for ten years until his former accomplice Lugaid killed him.
