Robert Leighton was a Scottish prelate and scholar, best known as a church minister, Bishop of Dunblane, Archbishop of Glasgow, and Principal of the University of Edinburgh from 1653 to 1662. He was "noted for his Christian piety, his humility and gentleness, and his devotion to his calling".

The Archbishop of Glasgow is an archiepiscopal title that takes its name after the city of Glasgow in Scotland. The position and title were abolished by the Church of Scotland in 1689; and, in the Catholic Church, the title was restored by Pope Leo XIII in 1878. In the Scottish Episcopal Church, it is now part of the Episcopal bishopric of Glasgow and Galloway.
