Sir John Young "Jackie" 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. 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."

He is well known in the United States as a colour commentator (pundit) of racing television broadcasts having worked in that role in the Indianapolis 500, Daytona 500 and the Monaco Grand Prix from 1971 to 1986. In 1976 Stewart became the play-by-play announcer 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.
