Antonio Ascari was an Italian Grand Prix motor racing champion. He won four Grands Prix before his premature death at the 1925 French Grand Prix. He was the father of two-time World Champion Alberto Ascari.

Grand Prix motor racing, a form of motorsport competition, has its roots in organised automobile racing that began in France as early as 1894. It quickly evolved from simple road races from one town to the next, to endurance tests for car and driver. Innovation and the drive of competition soon saw speeds exceeding 100 miles per hour (160 km/h), but because early races took place on open roads, accidents occurred frequently, resulting in deaths both of drivers and of spectators. A common abbreviation used for Grand Prix racing is "GP" or "GP racing".
