Argentines (mistakenly translated as "Argentinians" in the past); in Spanish Argentinos (masculine) or Argentinas (feminine) are people identified with the country of Argentina. This connection may be residential, legal, historical or cultural. For most Argentines, several (or all) of these connections exist and are collectively the source of their being Argentine.

Argentina is a multiethnic society, home to people of various ethnic, religious, and national origins, with the majority of the population made up of Old World immigrants and their descendants. As a result, Argentines do not equate their nationality with ethnicity, but with citizenship and allegiance to Argentina. Aside from the indigenous population, nearly all Argentines or their ancestors immigrated within the past five centuries. Among countries in the world that have received the most immigrants in modern history, Argentina, with 6.6 million, ranks second to the United States (27 million), and ahead of other immigrant destinations such as Canada, Brazil and Australia.
