The Legal system of Argentina is a Civil law legal system. The two pillars of the Civil system are the Constitution of Argentina (1853) and the Civil Code of Argentina (1871).

The Argentine Constitution of 1853 was an attempt to unite the unstable and young country of the United Provinces of the Rio de la Plata under a single law, creating as well the different organisms needed to run a country. The constitution was finally approved after failed signatory attempts in 1813 (see Assembly of 1813), 1819 and 1831 (Pacto Federal).

The Civil Code was written by Argentine jurist Dalmacio Vélez Sársfield, and started being effective on January 1, 1871. Beyond the influence of the Spanish legal tradition, the Argentine Civil Code was also inspired by the Draft of the Brazilian Civil Code, the Draft of the Spanish Civil Code of 1851, the Napoleonic code and the Chilean Civil Code among others. The sources of this Civil Code also include various theoretical legal works, mainly of the great French jurists of the 19th century. It was the first Civil Law that consciously adopted as its cornerstone the distinction between i. rights from obligations and ii. real property rights, thus distancing itself from the French model.

Argentina ⁱ/ˌɑrdʒənˈtiːnə/, officially the Argentine Republic (Spanish: República Argentina [reˈpuβlika aɾxenˈtina]), is a country in South America, the continent's second largest by land area, after Brazil. It is constituted as a federation of 23 provinces and an autonomous city, Buenos Aires. It is the eighth-largest country in the world by land area and the largest among Spanish-speaking nations.

Argentina's continental area is between the Andes mountain range in the west and the Atlantic Ocean in the east. It borders Paraguay and Bolivia to the north, Brazil and Uruguay to the northeast, and Chile to the west and south. Argentine claims over Antarctica, as well as overlapping claims made by Chile and the United Kingdom, are suspended by the Antarctic Treaty of 1961. Argentina also claims the Falkland Islands (Spanish: Islas Malvinas) and South Georgia and the South Sandwich Islands, which are administered by the United Kingdom as British Overseas Territories.

A recognised middle power, Argentina is Latin America's third-largest economy, with a "very high" rating on the Human development index. Within Latin America, Argentina has the fifth highest nominal GDP per capita and the highest in purchasing power terms. Analysts have argued that the country has a "foundation for future growth due to its market size, levels of foreign direct investment, and percentage of high-tech exports as share of total manufactured goods", and it is classed by investors as middle emerging economy. Argentina is a founding member of the United Nations, Mercosur, the Union of South American Nations, the Organization of Ibero-American States, the World Bank Group and the World Trade Organization, and is one of the G-15 and G-20 major economies.
