William Minto (10 October 1845 – 1 March 1893) was a Scottish man of letters.
He was born at Auchintoul, Aberdeenshire. He was educated at the University of Aberdeen, and spent a year at Merton College, Oxford. He was assistant professor under Alexander Bain at Aberdeen for some years; from 1874 to 1878 he edited the Examiner, and in 1880 he was made full professor of logic and English at Aberdeen.
On 8 January 1880 Minto married Cornelia, daughter of the Rev. Lewis Griffiths, rector of Swindon, Gloucestershire. He had two sons, William and Charles. The elder died during celebrations to mark the end of the First World War when a shell misfired.
