William Murray of Tullibardine, was a Scottish courtier and leader of the Clan Murray. William Murray was the son of William Murray of Tullibardine and Katherine Campbell, daughter of Sir Duncan Campbell of Glenorchy and Margaret Moncreiffe. When Lord Darnley was made Lord of Ardmanoch and Earl of Ross at Stirling Castle on 15 May 1565, he was one of 15 men who were made knights. On 9 August 1567 the English ambassador in Edinburgh Nicholas Throckmorton interviewed him, trying to work out the politics of his brother-in-law, the Earl of Mar, and the intentions of the Scottish lords towards the deposed and imprioned Mary, Queen of Scots. Tullibardine discussed how she was expendable to the Hamilton family's cause. Later that month, he and William Kirkcaldy of Grange took ships and chased James Hepburn, 4th Earl of Bothwell to Shetland, but the earl escaped. Tullibardine continued the pursuit for a time. Some of the ships came from Dundee, including the James, the Primrose, and the Robert. At the same time, his brother James Murray was made "customar" of Edinburgh, in place of James Curl, collecting taxes duties from merchants owed to the crown. Tullibardine was involved, requesting James Curl return some unlawfully impounded English cloth. Murray's sister was the influential Annabell Murray, Countess of Mar, who was the keeper of the young James VI of Scotland at Stirling Castle. There was a story, promoted by the secretary of Mary, Queen of Scots, John Lesley, that the king found the "testament of Bothwell" in Tullibardine's papers in 1577 and was pleased to hear a story that showed his mother as innocent, for a change. On 24 April 1579 the Earl of Atholl died shortly after attending a banquet at Stirling Castle. His wife Margaret Fleming,, was also unwell. A rumour started that they had been poisoned. Agnes Graham, the wife of William Murray of Tullibardine, wrote to Annabell Murray assuring her that the Countess of Atholl's complaints against her were "forged lies". He was Comptroller of Scotland. He resigned the office in 1580 and James VI gave it to his son John. He died in 1583.
