Giancarlo Ferretti (born 16 October 1941 in Lugo) is the former manager of the now-disbanded Italian professional road bicycle racing team Fassa Bortolo team, sponsored by the Italian cement company of the same name.
Fassa Bortolo was a top-ranked team until the 2005 season, during which it was part of the UCI ProTour. Among its former riders, it counted classics specialist Michele Bartoli, super-sprinter Alessandro Petacchi, stage racer Ivan Basso, Juan Antonio Flecha, time trial specialist Fabian Cancellara, and many others.
Ferretti went on to find a new sponsor for the team, and believed that Sony Ericsson was interested in sponsoring his team. However, on 14 October 2005, a man claiming to represent proposed new sponsor Sony Ericsson turned out to be an impostor, leaving all staff and riders unemployed.
His strong personality earned him the nickname the iron sergeant, and has been criticized by former riders for being too demanding, strict, and commanding. Uniquely in cycling, when he was the manager of Fassa Bortolo he was made an employee of Fassa Bortolo the company, and earned some respect for it.
