Don Cameron Thomson (born October 14, 1941) is an American water skier and a pioneer in the sport of barefoot skiing. He expanded early barefoot endurance records from 5 to over 30 minutes and introduced new maneuvers to the sport such as doubles barefooting, front to back and back to front turns, and participated in the development of the tumble turn with Terry Vance. Thomson was also a Master's rated 3 event skier, a proponent of water ski technology and of professional show skiing in the United States and Japan. He introduced backward barefooting to show skiing at Cypress Gardens in 1962, and was instrumental in the introduction of carbon fiber in molded skis, and the slalom fin.
