Sweden–United States relations

The relations between Sweden and the United States reach back to the days of the American Revolutionary War. The Kingdom of Sweden was the first country not formally engaged in the conflict (although around a hundred Swedish volunteers partook on the side of the Patriots) to recognize the United States before the Treaty of Paris. The Treaty of Amity and Commerce was signed subsequently in 1783 between Benjamin Franklin and Swedish representative Gustaf Philip Creutz.

In the 19th century, relations were largely cordial. Masses of Swedes emigrated to the United States from the 1840s–1920s, estimated at around a quarter of the Swedish population. The immigrants were eager for the promise of opportunity and land; many settled in the American Midwest. The result was a substantial Swedish American population. In the 20th century, the countries were fellow democracies (with the end of the Swedish monarchy's power after World War I) and maintained cordial if distant relations. Sweden maintained official neutrality but supplied nearby Nazi Germany during World War II, causing some tension with the Allies.

During the Cold War, Sweden did not join NATO and maintained a neutral status between the Western and Eastern Bloc, although its democratic and mixed capitalist approach was generally more in tune with the West and the United States. After the end of the Vietnam War, which was deeply unpopular in Sweden, relations between the two countries improved. The two countries have been largely friendly, and the United States supported Sweden's NATO membership. Under a comprehensive mandate, Sweden's nonalignment policy has led it to serve as the protecting power for the United States and to represent Washington in North Korea on consular matters. On 3 August 2022, the U.S. Senate unanimously approved Finland and Sweden's accession bids to join NATO. U.S. President Joe Biden approved the NATO membership of Finland and Sweden in August 2022.

Sweden's accession into NATO was finalized on 7 March 2024. The United States has observer status with the regional BEAC and CBSS.
