The following is a list of ambassadors of Brazil, or other chiefs of mission, to the United States of America.

[1] The title given by the Ministry of External Relations of the Federative Republic of Brazil to this position is currently "Ambassador Extraordinary and Plenipotentiary" (Portuguese: Embaixador Extraordinário e Plenipotenciário).

There have been fifty representatives of various ranks and titles from Brazil to the United States since diplomatic relations were inaugurated in 1824 to the present.

The United States of America was the second country[2] to recognize Brazil's Declaration of Independence, which was proclaimed in September 1822, by the regent, heir and crown prince to the throne of the former United Kingdom of Portugal, Brazil and Algarves, Dom Pedro of the House of Braganza.

The long Brazilian-North American diplomatic relationship and inter-continental friendship was founded on May 26, 1824,[2] when José Silvestre Rebello presented his diplomatic accreditation credentials as first Charge d'Affaires to fifth President James Monroe (1758-1831, served 1817-1825), at the newly restored Executive Mansion, now acquiring its new nickname and title of the White House, having been burned only a decade before by the invading British.
