Antonio Ascari (15 September 1888 – 26 July 1925) was an Italian Grand Prix motor racing champion.

Ascari was born at Bonferraro Di Sorgà, near Mantua but in the Veneto region of Italy, as the son of a wheat salesman.

[3] He drove the same car in the 1919 Targa Florio, and was performing well until he skidded off the racetrack into a deep ravine; despite this, his bosses took note of his talent and recruited him into the Alfa Romeo team.

[4] A month later, at the Cremona Circuit, he drove to his first major Grand Prix victory, driving an Alfa Romeo RL TF.

[4] He entered the 1923 Italian Grand Prix, where he was to drive the new P1 car, but the team withdrew from the race after Sivocci was killed during practice.

[6] On 26 July 1925, Ascari took part in the French Grand Prix at the Autodrome de Montlhéry, south of Paris.

He was leading the race when, on lap 23, he swerved at a left handed corner and got caught in some wooden fencing, which caused his car to overturn.

[7] Ascari's son, Alberto, who was seven at the time of Antonio's death, also became a racing driver, and was two-time Formula One champion in 1952–53.
