The Embassy of Argentina in Washington, D.C. is the Argentine Republic's diplomatic mission to the United States.

It is located at 1600 New Hampshire Avenue, Northwest, Washington, D.C.[1] The current Ambassador of Argentina to the USA is Alec Oxenford.

Located in the neighborhood of Dupont Circle and commissioned in 1906 by Pennsylvania Congressman George Franklin Huff, the mansion at 1600 New Hampshire Avenue NW was designed by Julian Abele (1881–1950), the first African-American graduate of the University of Pennsylvania's architecture program, when he was working with Horace Trumbauer.

The Argentine Government purchased the building on February 20, 1913, from Henrietta Huff, who decided to sell the house after her husband's death in 1912.
