Dargart mac Finguine (died 685) was a member of the Cenél Comgaill kindred, after which Cowal in Scotland is named. The only event directly connected with him in the Irish annals, based on a chronicle then being kept on Iona, is his death.
Dargart is believed to have been the father of two kings of the Picts, Bridei mac Der-Ilei and Nechtan mac Der-Ilei.
