Gillespie Roy Archibald Campbell, 4th Earl of Argyll (c. 1507 – 1558) was a Scottish nobleman and politician.
Campbell was the eldest son of Colin Campbell, 3rd Earl of Argyll (died 1529) and Jean Gordon, daughter of Alexander Gordon, 3rd Earl of Huntly. Immediately after succeeding to the title and offices of his father (in late 1529/early 1530), he was put in command of an expedition to quell an insurrection in the southern Scottish Isles. The voluntary submission of the main chiefs resulted; and Alexander of Islay, a prime mover in the insurrection, was able to convince King James V that he was personally well disposed to the government. More than that, he argued the disturbances in the Isles were chiefly because the earls of Argyll had made use of the office of lieutenant over the Isles for their own personal aggrandisement. Campbell was therefore summoned before the king to give an account of the duties and rental of the Isles received by him; and, as the result of the inquiry, was committed for a time to prison. Shortly afterwards he was liberated, but was deprived of his offices, and they were not restored to him until after the death of James V.
In a charter of 28 April 1542, Argyll is called "master of the king's wine cellar". Along with the Earls of Huntly and Moray he was named one of the council of the kingdom in the document which Cardinal Beaton produced as the will of James, and which appointed Beaton governor of the kingdom and guardian to the infant Mary, Queen of Scots. After the arrest of Beaton, on 20 January 1543, Argyll retired to his own lands to muster a force to maintain the struggle against the Earl of Arran, who had been chosen governor. Shortly afterwards the Earls of Argyll, Bothwell, Huntly, and Moray, supported by many of the barons and landed gentry, as well as by bishops and abbots, assembled at Perth, vowing their determination to resist the measures of the governor. On being summoned by the governor to disperse they did not resist; but when it became known that Henry VIII of England had succeeded in arranging a treaty of marriage between the young queen Mary and Edward, Prince of Wales, the Earls of Argyll, Huntly, Lennox, and Bothwell marched from Stirling with a force of ten thousand men, and compelled the governor to surrender to their charge, the infant queen, with whom they returned to Stirling.
