The Embassy of the United States in El Salvador is located in Antiguo Cuscatlán.

[2][3] The American Legation in San Salvador was opened under Minister Resident James R. Partridge on June 15, 1863.

[4] Following the 1931 Salvadoran coup d'état, normal relations between the United States and El Salvador were disrupted as the United States did not recognize the new revolutionary government, adhering to a policy of non-recognition of governments established via revolution, as outlined by a 1923 treaty.

[3] This non-recognition period ended on January 26, 1934, when the United States recognized the Martinez Government of El Salvador.

Diplomatic relations were restored, and on March 23, 1943, the United States raised the status of its legation in El Salvador to an embassy.
