Fernando Chacarelli (18 July 1905 – 26 April 1984) was an Argentinean runner who won eight medals at the South American athletics championships, including the gold medal in cross country running in 1931.

In 1924 he set a new Argentinean record over 3000 m, and in 1926–27 won a bronze and a silver medal in this event at the South American athletics championships.

Chacarelli believed he did not do so, and disappointingly withdrew from the cross-country event.

He retired the next year and later worked as a physical education teacher.

An annual marathon race is held in his honor in his native city of Cordoba.
