Bridei I, also known as Bridei, son of Maelchon, was king of the Picts from 554 to 584. Sources are vague or contradictory regarding him, but it is believed that his court was near Loch Ness and that he may have been a Christian. There were contemporaries claiming the title "king of the Picts". He died in the mid-580s, possibly in battle, and was succeeded by Gartnait son of Domelch.
