Gartnait (Gartnait mac Domnaill or Gartnait mac Dúngail) (died 663) was king of the Picts from 657 until 663.
He succeeded Talorgan mac Enfret on the latter's death in 657. The Pictish Chronicle king lists give him a reign of six or six and a half years, corresponding with the notice of his death in the Annals of Ulster and the Annals of Tigernach in 663.
The king lists record that he was succeeded by his brother Drest VI.
