Greek Argentines are Argentine citizens of Greek descent or Greek-born people who reside in Argentina. Despite not being as large as other Europe communities, the Greeks have contributed a lot to their new country. The first immigrants arrived at the end of the 18th century, while the bulk of immigration occurred during the first half of the 20th century.

Greek is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, Italy, southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Coptic, Gothic, and many other writing systems.
