Guerino Bertocchi (October 29, 1907 – April 13, 1981) was an Italian mechanic and racing driver known for his lifelong association with Maserati.

In 1957, he ran the car that gave Juan Manuel Fangio his third and fifth world titles.

Although officially employed as a running mechanic, Bertocchi would often share driving duties.

Bertocchi's best result was in 1953, when together with Emilio Giletti they finished sixth.

He then moved to De Tomaso Automobili, where he led the company client's car testing department.
