EU Delegation to the United States
Main Entrance EU Delegation to the United States

We promote EU policies in the United States, which includes presenting and explaining EU actions to the U.S. Administration and Congress.  By engaging with political actors, the media, academia, business, and civil society, we raise awareness of EU issues and concerns, and promote the importance of the EU-U.S. relationship among the American public.  We also analyze and report on the political, social, and economic situation in the U.S. to our headquarters in Brussels.

Since 1964, the EU has also maintained an office in New York, which now serves as the EU’s Delegation to the United Nations.

The European Union Delegation to the United States began in 1954 as a small two-person information office for the newly-formed European Coal and Steel Community (ECSC). Today, the EU Delegation is located at 2175 K Street NW and employs approximately 90 staff members, about 30 of whom are EU diplomats.
