Fíachu Finnolach: Fiacha Finnolach, son of Feradach Finnfechtnach, was, according to medieval Irish legend and historical tradition, a High King of Ireland.  He took power after killing his predecessor, Fíatach Finn.  He ruled for fifteen, seventeen, or twenty-seven years, depending on the source consulted, after which he, and the freemen of Ireland, were killed in an uprising of "aithech-tuatha" or "subject peoples", led, according to the "Lebor Gabála Érenn" and the "Annals of the Four Masters", by Elim mac Conrach, or by Cairbre Cinnchait according to Geoffrey Keating.  His wife Eithne, daughter of the king of Alba (Scotland), who was pregnant, fled home to Alba, where she gave birth to Fíachu's son, Tuathal Techtmar, who would ultimately return to Ireland to claim the throne.  The "Lebor Gabála Érenn" synchronises his reign with that of the Roman emperor Nerva (AD 96–98).  The chronology of Geoffrey Keating's "Foras Feasa ar Éirinn" dates his reign to AD 28–55, that of the "Annals of the Four Masters" to AD 39–56.

Hill of Tara: The Hill of Tara (, "Teamhair" or "Teamhair na Rí"), located near the River Boyne, is an archaeological complex that runs between Navan and Dunshaughlin in County Meath, Ireland.  It contains a number of ancient monuments and, according to tradition, was the seat of the High King of Ireland.

Conchobar Abradruad: Conchobar Abradruad ("red eyelashes"), son of Find File, son of Ros Ruad, son of Ferhus Fairgge, son of Nuadu Necht, of the Laigin, was, according to medieval Irish legend and historical tradition, a High King of Ireland.  He succeeded to the throne after the death of Lugaid Riab nDerg, and ruled for a year, at the end of which he was killed by Lugaid's son Crimthann Nia Náir.  The "Lebor Gabála Érenn" synchronises his reign with that of the Roman emperor Vespasian (AD 69–79).  The chronology of Geoffrey Keating's "Foras Feasa ar Éirinn" dates his reign to 13–12 BC, that of the "Annals of the Four Masters" to 9–8 BC.

Lugaid Lámderg: Lugaid Lámderg ("red hand"), son of Eochaid Uaircheas, was, according to medieval Irish legend and historical tradition, a High King of Ireland.  The "Lebor Gabála Érenn" says he reigned jointly with Conaing Bececlach, ruling the southern half of the island while Conaing ruled the north, after he killed the previous southern ruler, Conaing's brother Eochu Fíadmuine, while Keating and the Four Masters say he deposed Conaing when he killed Eochu and ruled the whole island.  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 (465–424 BC) 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.

Sírna Sáeglach: Sírna Sáeglach ("the long-lived"), 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 (694–665 BC), and his death with his successor Phraortes (665–633 BC).  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.

Cathair Mór: Cathair Mór ("the great"), son of Feidhlimidh Fiorurghlas, a descendant of Conchobar Abradruad, was, according to Lebor Gabála Érenn, a High King of Ireland.  He took power after the death of Fedlimid Rechtmar.  Cathair ruled for three years, at the end of which he was killed by the Luaigne of Tara, led by Conn Cétchathach.  The "Lebor Gabála Érenn" synchronises his reign with that of the Roman emperor Marcus Aurelius (161–180).  The chronology of Geoffrey Keating's "Foras Feasa ar Éirinn" dates his reign to 113–116, that of the "Annals of the Four Masters" to 119–122.

Fedlimid Rechtmar: Fedlimid Rechtmar ("the lawful, legitimate" or "the passionate, furious") or Rechtaid ("the judge, lawgiver"), son of Tuathal Techtmar, was, according to medieval Irish legend and historical tradition, a High King of Ireland.  His mother was Báine, daughter of Scál.  He took power after killing his predecessor, and his father's killer, Mal mac Rochride.  He is said to have instituted the principle of an eye for an eye into Irish law, after which the behaviour of the Irish improved.  The completion of the road construction around Tara is attributed to him.  He ruled for nine or ten years before dying in his bed, and was succeeded by Cathair Mór.  One of his sons, Conn Cétchathach, would succeed Cathair.  Two other sons, Fiacha Suighe, ancestor of the Dal Fiachrach Suighe, and Eochaid Finn, are named in medieval sources.  The "Lebor Gabála Érenn" synchronises his reign with that of the Roman emperor Marcus Aurelius (161–180).  The chronology of Geoffrey Keating's "Foras Feasa ar Éirinn" dates his reign to 104–113, that of the "Annals of the Four Masters" to 110–119.

Bodbchad: Badbchaid, son of Eochu Buadach, son of Dui Ladrach, was, according to late sources, briefly a High King of Ireland.  The "Lebor Gabála Érenn" says Bodbchad murdered his brother, the High King Úgaine Mór, who was succeeded directly by his son Lóegaire Lorc.  However, Geoffrey Keating and the "Annals of the Four Masters" agree that, after killing Úgaine, Bodbchad took the throne for a day and a half, after which Lóegaire killed him.  The "Lebor Gabála" synchronises Úgaine's reign to that of Ptolemy II Philadelphus (281–246 BC).  The chronology of Keating's "Foras Feasa ar Éirinn" dates Bodbchad's reign to 411 BC, that of the "Annals of the Four Masters" to 594 BC.

Eochaid Ailtlethan: Eochaid (or Eochu) Ailtlethan ("broad blade"), son of Ailill Caisfiaclach, was, according to medieval Irish legends and historical traditions, a High King of Ireland.  According to the "Lebor Gabála Érenn", he took the throne after overthrowing and killing the previous incumbent, Adamair, and ruled for eleven years, until he was killed in battle by Fergus Fortamail.  The "Lebor Gabála Érenn" synchronises his reign with that of Ptolemy V Epiphanes in Egypt (204–181 BC).  The chronology of Geoffrey Keating's "Foras Feasa ar Éirinn" dates his reign to 285–274 BC, that of the "Annals of the Four Masters" (which gives him a reign of seventeen years) to 414–396 BC.

Eochaid Faebar Glas: Eochaid Faebar Glas, son of Conmáel, was, according to medieval Irish legend and historical tradition, a High King of Ireland.  His epithet means "blue-green sharp edge".  According to the "Lebor Gabála Érenn", Geoffrey Keating's "Foras Feasa ar Éirinn" and the "Annals of the Four Masters", he came to power after killing the joint High King, Cermna Finn, in battle at Dún Cermna (Downmacpatrick in Kinsale, County Cork), and Cermna's brother and colleague Sobairce was killed by Eochaid Menn of the Fomorians (another version of the "Lebor Gabála" says he came to power at the end of a seven-year interregnum following the death of Tigernmas).  He killed Smirgoll, grandson of Tigernmas, in the battle of Druimm Liatháin.  He ruled for twenty years, until he was killed by Smirgoll's son Fiacha Labrainne in the battle of Carman.  The "Lebor Gabála" synchronises his reign with that of Piritiades in Assyria.  Keating's chronology dates his reign to 1115–1095 BC, that of the "Annals of the Four Masters" to 1493–1473 BC.
