Bizzarrini was an automotive manufacturer in the 1960s. Founded by former Ferrari engineer, Giotto Bizzarrini, the company built a number of automobiles before failing in 1969. The marque has been revived on a number of concept cars in the 2000s.

Although a number of names were used, most Bizzarrini products were variations of a single model, the A3C GT Strada. This entered production in 1965 and was later called the Grifo and 5300 GT before manufacturing ceased in 1969. A second model, the Europa, was also produced in low volumes. Bizzarrini also built a racing car, the P538, in 1966. The 1968 Manta concept car, designed by Giorgetto Giugiaro of ItalDesign, was a forerunner of Giugiaro's radical designs from the 1970s, including the Stratos.

The Bizzarrini factory also produced Giotto Bizzarrini's ASA compact car during this period.

After the Bizzarrini concern ended in 1969, the factory turned to producing the AMX.
