Juan Bielovucic (30 July 1889 – 14 January 1949) was a Peruvian aviator of Croatian and French descent who set several speed and altitude aviation records in 1910–13.
He was also the first person to complete a successful powered aircraft crossing of the Alps in 1913, following a 1910 attempt by his friend Jorge Chávez that ended in a fatal crash landing.
He established the first aviation school in South America in Lima, Peru.
