The history of ambassadors of the United States to Poland began in 1919.

Until the end of World War I, Poland had been partitioned between Russia, Germany, and Austria-Hungary.

After the war and the collapse of the empires, Poland became an independent republic in 1918.

The United States recognized the Second Polish Republic and established diplomatic relations.

Diplomatic relations were maintained throughout the years of World War II with the government-in-exile of Poland resident in London.
