John Graham, 4th Earl of Montrose

John Graham, 4th Earl of Montrose (1573–1626) was a Scottish nobleman, Earl of Montrose from 1608 to the 1620s. He was for a time Lord President of the Privy Council of Scotland.

He was a Catholic, as the English ambassador William Asheby noted in November 1589, on the death of his uncle Mungo Graham, Master Household to James VI.

On 31 January 1595, in a feud following the death of his kinsman John Graham of Hallyards, he fought with James Sandilands on the Royal Mile. There were over 100 pistol shots and Sandilands was wounded. In the confusion, a rumour spread that King James was besieged in Holyrood Palace. Sandilands' brother-in-law William Crauford, brother of the laird of Carse was killed.

He was at court in Royston in England in 1614 and the court physician Théodore de Mayerne treated him for melancholy. Mayerne offered to write a recipe to treat his wife's eyes in 1616.
