Mario Mazzacurati (21 October 1903 – 17 April 1985) was an Italian engineer and auto racer driver active in South Africa, winner of the 1936 South African Grand Prix in Bugatti cars with pseudonym Mario Massacuratti.
Born in Padua, he took a degree in geology at the University of Bologna and thus became an engineer and not a dentist as claimed by some sources.
Sometime near 1930 he moved to South Africa for civil engineering work including building Hout Bay Harbour and roads through country towns.
He bought a lot of ex-Nuvolari cars and it is rumoured that he indeed was a cousin of Tazio Nuvolari but not confirmed.
Despite being a national sporting hero, as an Italian he was interned in South Africa during World War II but made a daring escape from the concentration camp.
