The United States ambassador to Sweden (Swedish: Förenta Staternas ambassadör i Sverige) serves as the official diplomatic representative of the United States to the King and the Government of the Kingdom of Sweden.

Diplomatic relations between Sweden and the United States began with the signing of the Treaty of Amity and Commerce in 1783.

Sweden received its first U.S. resident minister in 1814, but in 1818, the senior U.S. diplomat again became the chargé d'affaires.

In 1854, the senior American diplomat in Sweden again became the minister resident.

The contemporary tendency of American presidents is to appoint fundraisers or prominent campaign supporters to the ambassador's post in Sweden, rather than promoting career members of the United States Foreign Service.
