The Gaelic surname Mac Suibhne is a patronymic form of "Suibhne" and means "son of "Suibhne"".

Artúr Dall Mac Gurcaigh was a Scottish poet.
 He was the author of "Dál chabhlaigh ar Chaistéal Suibhne" ("An arranging of a fleet against Castle Sween"), written c. 1310 during the Wars of Scottish Independence.
 The poem is one of the few Scottish vernacular poems before the mid-14th century, and tells of Eoin mac Suibhne, enemy of King Robert I of Scotland, and head of "Clann Suibhne" (the MacSweens) - a clan who would be expelled from Scotland and flourish as a mercenary clan in Ireland.
Clan Sweeney is an Irish clan of Scottish origin.
 The Mac Suibhne family did not permanently settle in Ireland before the beginning of the 14th century, when they became Gallowglass soldiers for the O'Donnell dynasty of Tyrconnell.
 The clan also claims an Irish descent from a prince of the O'Neill dynasty, Ánrothán Ua Néill, son of Áed, son of Flaithbertach Ua Néill, King of Ailech and Cenél nEógain, died 1036.
 Through this descent the clan can claim a descent from Niall Noigíallach ("Niall of the Nine Hostages").

The gallowglasses (also spelt galloglass, gallowglas or galloglas; from Irish: "gall óglaigh" meaning foreign warriors) were a class of elite mercenary warriors who were principally members of the Norse-Gaelic clans of Scotland between the mid 13th century and late 16th century.
 As Scots, they were Gaels and shared a common background and language with the Irish, but as they had intermarried with the 10th century Norse settlers of western Scotland, the Irish called them "Gall Gaeil" ("foreign Gaels").
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.
 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.
Aodh Mac Cathmhaoil, O.F.M., (Latin: Hugo Cavellus; anglicised: Hugh MacCaghwell) (1571 – 22 September 1626), was an Irish Franciscan theologian and Archbishop of Armagh.
 He was known by Irish speakers at Louvain by the honorary name "Aodh Mac Aingil" ("Mac Aingil" is Irish for "Son of an Angel"), and it was under this title that he published the Irish work "Scáthán Shacramuinte na hAthridhe".
Murchadh Mac Suibhne (died 1267) was a prominent 13th-century noble.
 Murchadh was a son of Maol Mhuire an Sparáin, son of Suibhne, eponymous ancestor of the Clann Suibhne.
 Murchadh led the dispossessed clan pressed into King Hakon IV of Norway's service during King Hakon's 1263 expedition.
 Clann Suibhne were required to surrender hostages to King Hakon as guarantee for their support.
 Murchadh was granted Arran, however these lands were lost shortly after the Battle of Largs and he appears to have fled to Ireland.
 He was taken prisoner by Domnall Mac Maghnusa in 1265 and was imprisoned by Walter de Burgh, Earl of Ulster and died shortly afterwards.
