Sir Peter George Snell (17 December 1938 – 12 December 2019) was a New Zealand middle-distance runner. He won three Olympic gold medals, and is the only male since 1920 to have won the 800 and 1500 metres at the same Olympics, in 1964.
Snell had a relatively short career as a world-famous international sportsman, 1960–1965, yet achieved so much that he was voted New Zealand's "Sports Champion of the (20th) Century" and was one of 24 inaugural members of the International Association of Athletics Federations Hall Of Fame named in 2012. A protégé of the New Zealand athletics coach Arthur Lydiard, Snell is known for the three Olympic and two Commonwealth Games gold medals he won, and the several world records he set.
He is also known as Peter George Snell, Sir Peter George Snell and Sir Peter Snell.
