Italian Argentines (Italian: Italo-argentini, Spanish: ítalo-argentinos) are Argentine-born citizens of Italian descent or Italian-born people who reside in Argentina. After Spain, Italy is the second largest ethnic origin of modern Argentines. It is estimated up to 25 million Argentines have some degree of Italian descent (up to 62.5% of the total population), Italians began arriving in Argentina in great numbers from 1857 to 1940, totaling 44.9% of the entire post-colonial immigrant population; more than from any other country (including Spain at 31.5%), and this migratory flow continued to the early 1950s, with Italy also having the most emigrants to Argentina for the decades 1980–2000.
