Salvador Mazza (June 6, 1886 – November 9, 1946) was a noted Argentine physician and epidemiologist, best known for his strides in helping control American trypanosomiasis, an endemic disease among the rural, poor majority of early 20th century South America.

A precocious student, Mazza was accepted into the prestigious, public college preparatory school, the Colegio Nacional de Buenos Aires, at age ten.

He organized and briefly directed the quarantine facility for cholera-stricken seafarers and immigrants on Martín García Island, and then performed his medical residency in a number of European hospitals before earning his degree of Doctor of Medicine and returning to Argentina, in 1910.

Returning to Argentina in 1925, Mazza was given a prominent post in the UBA Surgical Clinic and shortly afterwards invited Nicolle to Buenos Aires, where they discussed the need for more vigorous action against the contagious diseases affecting the country's poor.
