Cáelbad (Cáelbhadh, Caolbhadh, Caolbhaidh), son of Cronn Badhraoi, a descendant of Mal mac Rochride, was, according to Lebor Gabála Érenn, a High King of Ireland for a period of one year. Inneacht daughter of Lughaidh was the mother of Caolbhaidh son of Cronn Badhraoi; and he was slain by Eochaid Mugmedon. The chronology of Geoffrey Keating's Foras Feasa ar Éirinn dates his reign to 343–344, that of the Annals of the Four Masters to 356–357.

According to Foras Feasa ar Éirinn, Caolbhaidh was a son of Cronn Badhraoi, son of Eochaidh Cobha, son of Lughaidh, son of Rossa, son of Iomchaidh, son of Feidhlimidh, son of Cas, son of Fiachaidh Aruidhe, son of Aonghus Gaibhnionn, son of Fearghus Foghlas, son of Tiobraide Tireach, son of Breasal, son of Fearb, son of Mal, son of Rochruidhe, son of Cathbhadh, son of Giallchaidh, son of Cunnchaidh, son of Fionnchaidh, son of Muireadhach, son of Fiachaidh Fionnamhnus, son of Irial Glunmhar, son of Conall Cearnach of the race of Ir son of Milidh.

The Macalister translation of Lebor Gabála Érenn says that Cáelbad was also King of Ulster when he killed Muiredach Tirech to take the Kingship. It also says that he took the kingship of Ireland for a space of one year, and exacted the Boroma, a cattle tax, without a battle. And he fell at the hands of Eochaid Mugmedon. Cáelbad also had a son, Fíachna Lonn mac Cóelbad, who was a King of the Dál nAraidi.
