Roberto Nosetto (died 21 February 2013) was an Italian businessman who was the team principal of Ferrari during the 1977 season as well as working as the circuit director for the Imola Circuit and the race director for MotoGP.
Nosetto was born in Turin, and studied mechanical engineering at the Politecnico di Torino and then joined the Commissione Sportiva Automobilistica Italiana (CSAI), the Italian national sporting authority, to write its regulations and oversee the safety of cars and circuits. He was hired to act as the Team Principal of the Ferrari team during the 1977 Formula One Season. Under Nosetto's solitary year as Team Principal of Ferrari, the team was able to win both the Drivers' and Constructors Championship with Niki Lauda taking the crown for the team. However despite this success, Nosetto and Lauda did not get along and cooperation between the two steadily decreased throughout the season. At the end of the season, Nosetto was dropped as team manager in favor of Marco Piccinini. Despite this, Nosetto was kept as a close advisor to Enzo Ferrari, and became the director of Ferrari's test track at Fiorano.
During the 1980's Nosetto became the Director of the Autodromo Enzo e Dino Ferrari Formula One circuit conducting the organisation of the San Marino Grand Prix until the mid-1990's. In 1994 Nosetto became one of the lead crash investigators when Williams engineers Patrick Head and Adrian Newey were charged for manslaughter being held accountable for the Death of Ayrton Senna at the 1994 San Marino Grand Prix. Nosetto and the other investigators concluded that it was a steering column failure that caused Senna's fatal accident. Both Head and Newey were acquitted of manslaughter in 1995 by an Italian Magistrate.
After Nosetto's tenure as the circuit director of the Imola Circuit, he became the Race Director of the MotoGP and World Superbike Championship. Nosetto held this position until 2004 when he finally opted to retire from his motor racing career.
Nosetto died on the 21st February 2013 at his home in Gallipoli, Italy.
