William Murray, 2nd Earl of Tullibardine (c. 1574–1626) was a Scottish landowner and courtier.
He was the son of John Murray, 1st Earl of Tullibardine and Catherine Drummond, daughter of David, 2nd Lord Drummond.
He travelled abroad in 1594 to learn languages, first going to London with James Drummond of Innerpeffray, and William Drummond, with a passport from the English ambassador Robert Bowes. According to the English diplomat George Nicholson, James VI he and James Drummond of Inchaffray were made servants in the king's chamber in August 1601 at Perth.
He came to London with James VI and I in 1603. Lady Anne Clifford wrote that in July 1603, "Now was the Master of Orkney and the Lord Tullibardine much in love in Mrs Cary and came thither [to Norbury, where they were isolated because of illness] to see us with George Murray in their company who was one of the King's bedchamber."
On 14 March 1617 King James wrote to him from Whitehall Palace requesting his help preparing for his visit to Scotland. James wanted capercaillies and ptarmigans sent to Durham and to other stops on his way to Berwick-upon-Tweed, as examples of rare and precious Scottish cuisine.
Murray married married firstly in 1599 Cecilia Wemyss. It has been suggested that a sonnet by the king, Nocht Orientall Christall Streemes, was addressed to Cecilia.
His second wife, married in 1604, Dorothea Stewart, was the daughter of John Stewart, 5th Earl of Atholl. Their children included:
- Mary Murray, who married Sir John Moncrieffe of Moncrieffe.
- John Murray (d. 1642) became Earl of Tullibardine in 1626 and Earl of Atholl in 1629.
