Suibhne mac Duinnshléibhe was a late 12th-century, and early 13th-century, lord in Argyll. He does not appear in contemporary records, although his name appears in the patronymic names of two of his sons. Suibhne appears in the 16th century Leabhar Chlainne Suibhne, which documents the early history of Clann Suibhne. This account claims that he is the ancestor of Irish clan, and that he was the builder of Castle Sween in Knapdale, Argyll. However, other sources suggest the castle was built in the late 11th century by Suibhne MacAnrahan, brother of the High King of Ireland. Suibhne is said to be identical to the "Swineruo", or Suibhne Ruadh ("Suibhne the Red"), recorded in the Ane Accompt of the Genealogie of the Campbells, a 17th-century Clan Campbell genealogy.
