Eochaid mac Condlai (died 553)[1] was a king of Ulaid from the Dal nAraide.
[2] He belonged to the main ruling dynasty of the Dal nAraide known as the Uí Chóelbad based in Mag Line, east of Antrim town in modern county Antrim.
He succeeded Cairell mac Muiredaig Muinderg of the Dal Fiatach as king of Ulaid.
The annals state that he was ancestor of the Ui Echach of Ulaid.
[4] It is more probable they descended from a brother of Eochaid's grandfather, Cáelbad mac Crond Ba Druí, named Eochu.
