Fland mac Máele Tuile (died 700), also Flann Finn or Flann Albus was a King of Ailech and head of the Cenél nEógain branch of the northern Uí Néill.
He was the grandson of Crundmáel mac Suibni (died circa 660), a previous King of Ailech and greatgrandson of the high king of Ireland Suibne Menn (died 628).
In 681, along with his allies the Cianachta Glenn Geimin (in modern County Londonderry), he defeated the incumbent king of Ailech, Máel Dúin mac Máele Fithrich of the Cenél maic Ercae, who was slain at the Battle of Bla Sléibe (in modern County Londonderry).
[3] In 700 the annals record the expulsion of Urthuile from the kingship and he went to Britain.
The genealogies give Fland a son named Díchon whose great-great grandson Máel Pátric was founder of the Kilpatricks, who possessed districts in the east of Tyrone.
