Alejandro de Tomaso (10 July 1928 in Buenos Aires – 21 May 2003 in Modena, Italy) was an Argentine racing driver and businessman.

In 1955, de Tomaso was implicated in a plot to overthrow Argentine president Juan Perón, and fled to Italy.

In 1957, he started his career in the car industry as a Formula One racing driver for Scuderia Centro Sud, a privateer team based in Modena.

He drove in the first race of the Formula One World Championship of Drivers, the 1957 Argentine Grand Prix, driving a Ferrari 500, finishing 9th.

Starting in 1963, De Tomaso Modena also built high-performance sports cars, most of which used aluminium backbone chassis, which were to become the company's technical trademark.

These included the Ghia and Vignale coachbuilding studios, the Benelli and Moto Guzzi motorcycle firms, the Innocenti car company (founded as an offshoot of the British Motor Corporation to build Minis in Italy), and in 1975, the celebrated sports car maker Maserati, which was rescued from bankruptcy with the assistance of the Italian government.
