Niall Glúndub mac Áedo (Modern Irish: "Niall Glúndubh mac Aodha") (died 14 September 919) was a 10th-century Irish king of the Cenél nEógain and High King of Ireland. Many Irish kin groups were members of the Uí Néill and traced their descent from Niall of the Nine Hostages (Niall Noígiallach). 
His mother was Máel Muire, daughter of Kenneth MacAlpin, King of Scots.
Biography.
Son of Aed Finliath, Niall is first recorded succeeding his brother Domnall mac
his death in 915.
Benjamin Hudson suggested that it was only the vigorous campaigning by Niall Glúndub in Ulster and Connacht from 913 to 915, along with Óengus's fortuitous death, that led to Niall being named Flann's heir. Alex Woolf suggested that Flann had not only attempted to monopolise the succession within his family, but had come close to instituting a national kingship in Ireland comparable to that created by his contemporaries Alfred the Great and Edward the Elder in England from their Kingdom of Wessex.
