Which country is the largest Spanish-speaking country by area?

Argentina is the largest Spanish-speaking country in the world by area.

Located in the southern half of South America, Argentina covers about 2,780,085 square kilometres of internationally recognised territory. Its long north–south shape runs from subtropical areas near Bolivia and Paraguay to Tierra del Fuego and the sub-Antarctic islands, giving the country exceptionally varied climates and landscapes.

Spanish is spoken by almost all Argentines, and the country is especially associated with Rioplatense Spanish, the variety heard around Buenos Aires and the Río de la Plata. Argentine Spanish commonly uses voseo, addressing someone with vos rather than tú, and has distinctive vocabulary and pronunciation influenced partly by immigration.

A frequent mistake is choosing Mexico because it has the world’s largest Spanish-speaking population. Mexico is indeed the most populous Spanish-speaking country, but Argentina is larger in area. Colombia, Peru and Spain are also Spanish-speaking nations, yet each has a smaller total area than Argentina.
