Alexander Lindsay, 1st Earl of Balcarres (6 July 1618 – 30 August 1659) was a Scottish nobleman and courtier.
Originally a strong supporter of the Covenant, having been tutored at the University of St. Andrews by David Forret, he was present at the Battle of Marston Moor in 1644.
However, in 1648 he became an Engager seeking an alliance with Charles I, leading to a break with the majority of the Covenanters.
He was created Earl of Balcarres on 9 January 1651, with the subsidiary title Lord Lindsay and Balneil, and hereditary governor of Edinburgh Castle in 1651.
He visited France to advise the king in 1653 and 1654 and finally resided at the court in exile of Charles II in the Netherlands.
