Giovanni Giuseppe Gilberto "Nanni" Galli (2 October 1940 – 12 October 2019) was an Italian saloon, sports-car and Formula One driver of the 1960s and 1970s.

Born in Bologna, Galli started his career in endurance racing. He won the Circuit of Mugello race in 1968 and finished second in the Targa Florio (with Ignazio Giunti) the same year. In the 1968 24 Hours of Le Mans, Galli and Giunti finished 4th in an Alfa Romeo T33/2. The following year at Le Mans, he shared a drive with Robin Widdows and they finished 7th in a Matra. Galli's final appearance at Le Mans was in 1970, where he shared a Alfa Romeo T33/3 with Rolf Stommelen. They did not finish.

Galli moved briefly into Formula One in 1970, debuting in the 1970 Italian Grand Prix with a McLaren-Alfa, and had a handful of drives over the next couple of years, finishing 3rd in the non-championship Grand Prix of the Italian Republic at Vallelunga in 1972 for the small Tecno team.

His one shot at the big time came that year when he drove for Ferrari in the 1972 French Grand Prix at Circuit Charade near Clermont-Ferrand. Galli qualified 20th and finished only 13th. After half a dozen outings in an uncompetitive car for Frank Williams the following year, Galli announced his retirement.

Galli participated in 20 World Championship Grands Prix in total, scoring no championship points.

In 2014 Galli participated in the Le Mans Classic in a Lola T290 finishing 21st. He had not entered a race since he drove in the 1974 World Endurance Championship with an Osella-Abarth.

Galli died on 12 October 2019 in Prato at the age of 79.
