John Douglas (14 July 1721 – 18 May 1807) was a Scottish scholar and Anglican bishop.
Early life and education
Douglas was born at Pittenweem, Fife, the second son of shopkeeper Archibald Douglas, and Isabel, daughter of Robert Melvill of Carsendor. His father was later Wagon-Master-General to the British Forces and died at the Battle of Dettingen in Frankfurt in 1743. Douglas was educated at Dunbar, East Lothian, and at Balliol College, Oxford, where he gained his M.A. degree in 1743. They had one son, Rev. William Douglas (1768–1819), Archdeacon of Wilts from 1799 to 1804.
A sister of his kept the British Coffee House, one of London's significant meeting places, especially for Scotsmen.
