Foreign relations between Argentina and Greece have existed for about half a century. Both countries are represented by an embassy in the other one's capital. According to the Greek foreign ministry, at least 50,000 persons of Greek descent live in Argentina with about 5,000 with Greek passports. The majority of Greeks live in Buenos Aires.

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.
