Justin Neville Norris (born 3 June 1980) is an Australian butterfly and individual medley swimmer, who won the bronze medal in the 200 m butterfly at the 2000 Sydney Olympics.
Coming from Stockton, New South Wales, Norris relocated to the Australian Institute of Sport, Canberra in 1999 after being awarded a scholarship. He subsequently gained selection for Australia at the 1999 Pan Pacific Championships in Sydney. At his first Olympics in Sydney, Norris made a poor start, missing the final of the 400 m individual medley. However, he qualified for the final of the 200 m butterfly, where he was considered an outsider. Having nothing to lose, Norris attacked from the start, contesting the lead over the first 100 m. Willed on by a partisan home crowd, he managed to hang onto third position as the favourites surged for the finished line. While being interviewed on the pooldeck, a bewildered Norris repeatedly used what has become his winning catchphrase - I'm stoked.
