David Millar (born 4 January 1977) is a Scottish road racing cyclist riding for Garmin-Sharp. He has won four stages of the Tour de France, five of the Vuelta a España and one stage of the Giro d'Italia. He was the British national road champion and the national time trial champion, both in 2007. He is the only British rider to have worn all Tour de France jerseys and one of six to have worn the yellow jersey. He was also the first (of two) British riders ever to have worn the leader's jersey in all three Grand Tours. He was banned for two years in 2004 after admitting taking banned performance-enhancing drugs, but four years after his return he won the silver medal at the World Time Trial Championships. He is not related to fellow Scottish cyclist Robert Millar.
