Conchobar[1] mac Nessa (son of Ness) is the king of Ulster in the Ulster Cycle of Irish mythology. He rules from Emain Macha (Navan Fort, near Armagh). He is usually said to be the son of the High King Fachtna Fáthach, although in some stories his father is the druid Cathbad, and he is usually known by his matronymic, mac Nessa: his mother is Ness, daughter of Eochaid Sálbuide, King of Ulster.
Conchobar was an important figure in the Ulster Cycle, appearing in the Táin Bó Cúailnge and a number of other stories where he is depicted as a good king.[2]
