Argentina is home to the fourth largest Estonian community in the Americas, behind the United States, Canada and Brazil.

There are approximately 1,100,000 Estonians in the world, of which 930,000 live in Estonia representing 85% of the total, the remaining 15% is distributed primarily in Finland, the United States, Canada, Sweden, and Russia.

[citation needed] There are organised groups of Estonians in more than 20 countries such as Argentina, Australia, Austria, Brazil, Canada, the United Kingdom, Finland, France, Germany, Latvia, Lithuania, the Netherlands, New Zealand, Norway, Portugal, Russia, South Africa, Sweden, Switzerland, Ukraine and the United States.

[7][8][9] The Estonian community led to the Evangelical Lutheran Congregation "The Reformation" (Spanish: La Reforma) over 55 years ago.

On October 13, 1970 a public worship was held in the Temple[10] with the German Congregation; this marked the beginning of the Parish Community Centre of Olivos.
