Drest son of Donuel was king of the Picts from c. 663 until 672. Like his brother and predecessor Gartnait son of Donuel, and Gartnait's predecessor Talorgan son of Eanfrith, he may have reigned under the overlordship of the Northumbrian king Oswiu. Gartnait and Drest may have been sons of Domnall Brecc, who was king of Dál Riata from c. 629 until he was killed in 642.
