The Cenél Conaill, or "kindred of Conall", are a branch of the Northern Uí Néill, who claim descent from Conall Gulban, son of Niall of the Nine Hostages, and allegedly the first Irish nobleman to convert to Christianity. Their kingdom was known as Tír Conaill, with their powerbase at Mag Ithe in the Finn valley, however they gradually expanded to cover what is now counties Donegal and Fermanagh. The Cenél Conaill clashed regularly with their kin the Cenél nEogain, eventually capturing the latter's original power-base of Ailech in the Inishowen peninsula—in modern-day County Donegal—by the 12th century.

Below is a list of their principle clans and septs.

Cenél Luighdech The Cenél Luighdech (more commonly known as Sil Lugdach) descend from Lugaid mac Sétnai, the great-grandson of Conall Gulban. Their tribal territory extended from Dobhar (Gweedore) to the river Suilidhe (Swilly) in County Donegal. The O'Donnells and O'Dohertys who descend from this branch, were the two principal and most powerful septs of the Cenél Conaill. The most famous descendant of the Cenél Conaill is Saint Columba, who founded the monastery at Derry, and is claimed as being the grandson of Conall Gulban.
