Colin Campbell, 6th Earl of Argyll (c. 1542– October 1584) was a Scottish nobleman and politician. He was appointed to the Lord Chancellorship of Scotland.
He was the eldest son of Archibald Campbell, 4th Earl of Argyll and his second wife Margaret Graham. He was a younger half-brother of Archibald Campbell, 5th Earl of Argyll. His maternal grandparents were William Graham, 3rd Earl of Menteith and Margaret Moubray.
Argyll made a progress in Lorne, Argyll, and Cowal in July 1574 holding courts and executing those convicted of "slaughter, murder, theft, or common sorcery." Around 160 people were executed by hanging. Some "women and men suspected of witchcraft and sorcery were apprehended" and kept in prison or released on caution, until further trial. Argyll also ensured churches had ministers or readers teaching the Bible in Scottish Gaelic as translated by the late John Carswell, Bishop of the Isles. He sought the resolution of feuds between Aonghus MacDonald of Kintyre and Lachlan Mor Maclean, and MacConnell Gorm, Lord of the Isles, and the Laird of Glengarry.[1]
