Sir John Young Stewart, OBE (born 11 June 1939) is a British former Formula One racing driver from Scotland. Nicknamed the "Flying Scot", he competed in Formula One between 1965 and 1973, winning three World Drivers' Championships, and twice runner-up, over those nine seasons. He also competed in Can-Am. In 2009 he was ranked fifth of the fifty greatest Formula One drivers of all time by journalist Kevin Eason who wrote: "He has not only emerged as a great driver, but one of the greatest figures of motor racing." In the United States, he worked as a color commentator on television broadcasts at the Indianapolis 500, Daytona 500 and the Monaco Grand Prix from 1971 to 1986. In 1976, Stewart was a play-by-play announcer for ABC Sports for the 1976 Winter and 1976 Summer Olympics, and he served as host of the Indianapolis 500 coverage for ABC's Wide World of Sports and ABC Sports, from 1982 to 1984. He has also been a spokesman for Ford, Rolex and Moët. Between 1997 and 1999, in partnership with his son, Paul, he was team principal of the Stewart Grand Prix Formula One racing team.
