James Graham, 1st Marquess of Montrose (1612 – 21 May 1650) was a Scottish nobleman, poet and soldier, lord lieutenant and later viceroy and captain general of Scotland. Montrose initially joined the Covenanters in the Wars of the Three Kingdoms, but subsequently supported King Charles I as the English Civil War developed. From 1644 to 1646, and again in 1650, he fought in the civil war in Scotland on behalf of the King. He is referred to as the Great Montrose.
