Since 1840, the United States has had diplomatic representation in the Italian Republic and its predecessor nations, the Kingdom of Sardinia and then the Kingdom of Italy, with a break in relations from 1941 to 1944 while Italy and the U.S. were at war during World War II. The U.S. Mission to Italy is headed by the Embassy of the United States in Rome, and also includes six consular offices.

Beginning in 2006, the U.S. ambassador to Italy is concurrently accredited as the U.S. ambassador to San Marino.
