List of Ambassadors of the United Kingdom to Argentina

The Ambassador of the United Kingdom to Argentina is the United Kingdom's foremost diplomatic representative in Argentina, and head of the UK's diplomatic mission there. The official title is Her Britannic Majesty's Ambassador to the Argentine Republic.

From 1982–1992, following the Falklands War, there were no diplomatic relations between the UK and Argentina. There was no Ambassador, but the embassy building remained open, as the British Interest Section of the Swiss Embassy, rather than as the British Embassy. The Argentine Embassy in London came under the Brazilian flag during the same period. Diplomatic relations were restored in 1990.
