Argentina–Spain relations

Argentina–Spain relations are the bilateral relations between the Argentine Republic and the Kingdom of Spain. Since a great portion of the immigrants to Argentina before the mid-19th century were of Spanish descent, and a significant part of the late-19th century/early-20th century immigrants to Argentina were Spaniards, the large majority of Argentines are at least partly of Spanish ancestry. Both nations are members of the Organization of Ibero-American States and the United Nations.
