John Nichol (8 September 1833 – 11 October 1894), was a Scottish literary academic, and the first Regius Professor of English Language and Literature at the University of Glasgow.
Born in Montrose, Scotland, Nichol was the son of John Pringle Nichol, Regius Professor of Astronomy at the University of Glasgow. John Jr. studied first at Glasgow (1848–55) and then Balliol College, Oxford (1855–9) as a Snell Exhibitioner, graduating with a First-Class degree in Classics, Philosophy and Mathematics. After graduating, Nicholl remained at Oxford as a coach. With Albert Venn Dicey, Thomas Hill Green, Swinburne and others, he formed the Old Mortality Society for discussions on literary matters.
In 1862 he was made Regius Professor of English Literature at Glasgow. He had already made a reputation as an acute critic and a successful lecturer, and his influence at Glasgow was very marked. During his tenure as Regius Professor, he also lectured at Oxford University as well as private tutoring across Britain, and formed a strong reputation as an inspiring lecturer, later joining Glasgow's Dialectic Society.
He left Glasgow for London in 1889, and died on 11 October 1894. A Memoir by Professor Knight was published in 1896.
