This article lists the kings and lords of Clandeboye (Irish: Clann Aodha Buídhe), a Gaelictúath of the Cenél nEógain, located in the eastern part of Ulster in the north of Ireland. They are listed from their date of ascension to date of death, unless otherwise stated.[1]
Murtagh Dulenaach O'Neill was the last to claim overlordship of all Clandeboye. During his reign the sons of Phelim Bacagh and Niall Oge founded their own lordships at Murtagh's expense, reducing him to lord in name only. The Annals of the Four Masters regarded Hugh, son of Niall Oge, as lord of Clandeboye until his death in 1555.
