The Ambrosini S.1001 Grifo ("Griffin") was an Italian light airplane that appeared shortly after the end of World War II.

From 28–29 April 1948, Leonardo Bonzi and Maner Lualdi established a distance record for aircraft in this class, flying from Campoformido, Italy to Massawa, Eritrea - 4,650 km (2,890 mi) without stopover.

On January 10, 1949, on board the same aircraft, now christened Angelo dei Bimbi, they headed for Dakar in an attempt to reach South America.

By the end of a triumphal tour through Brazil, Uruguay and Argentina, they had collected 500 million lire from the Italian community living in these countries to contribute to the economic restarting of Italy.

A two-seater version powered by a de Havilland Gipsy Major of 120 kW (160 hp) was offered to the AMI as a trainer.
