Robert Leighton, a Scottish prelate, born in Edinburgh in 1611, died in London, June 26, 1684. He was educated at the university of Edinburgh, in 1641 became pastor of a Presbyterian church, and in 1653 principal of the university of Edinburgh. On the accession of Charles II. an attempt was made to establish episcopacy in Scotland. Leighton was favorably disposed toward the system, though his father had been savagely persecuted by Laud for his opposition to it; and, in the hope of moderating the violent dissensions of the time, he reluctantly consented to accept a bishopric, choosing that of Dumblane as being one of the poorest in revenue. In 1670, on the resignation of Sharpc, he was transferred to the archbishopric of Glasgow; but finding himself unequal to the difficulties of his new dignity, he resigned it in 1674, retired to England, and spent his remaining days in that country. He left various works, the best known of which is his "Practical Commentary on the First Epistle General of St. Peter." A complete edition of his writings appeared in 1808 (6 vols. 8vo, London). Among other editions is that by Pearson (London, 1828, and New York, 1859); the latest edition was published in London in 1871, in 6 vols.
