Sir William Galloway (12 February 1840 – 2 November 1927) was a Scottish mining engineer, professor and industrialist. He spent much of his life as an Inspector of Mines, before being offered the post of Professor of Mining at the University College of Wales. His life was spent improving the lot of miners and working to determine the causes of explosions and accidents in mines and finding ways of preventing them or alleviating their impact. His efforts were recognised in 1924, when, at the age of 83, he was knighted.
