Guillermo Ortelli (born in Salto, Buenos Aires Province on April 25, 1973) is an Argentine race car driver, who currently is competing in several domestic series.

[1] After having some success in football (he played for homecity's Club Sports Salto until 5th division and was champion once) he started his career in motor racing.

The two-year period in Formula Renault meant an opportunity to drive a Tulio Crespi's Ford Escort XR3 in TC2000 series.

The conflict between ACTC and CDA (ACA) meant that he could not compete in TC2000 (he was planned to partner Juan María Traverso and Lucas Armelini in Toyota team).

He returned to new-born Top Race V6 in 2005, driving a Chevrolet Vectra sponsored by Club Atlético Boca Juniors.
