Libero Liberati (20 September 1926 – 5 March 1962) was an Italian former professional motorcycle road racer. He competed in the FIM Grand Prix motorcycle racing world championships from 1952 to 1959, most prominently as a member of the Gilera factory racing team where he won the 500cc world championships.
Liberati was born in Terni. He became famous in his country, winning the Italian championship in 1948. Two years later Moto Guzzi called him to race in the 500cc World Championship, where he took part in a single race. The same happened the following year with Gilera. Liberati scored his first points in the World Championship in 1953, and his first race victory came in 1956 in the 350cc class.
