The Republic of Poland Ambassador to the United States (known formally as the Ambassador Extraordinary and Plenipotentiary of the Republic of Poland to the United States) is the official representative of the Government of the Republic of Poland to the Government of the United States.

The first permanent Polish diplomatic mission was created in late 18th century by the last king of Poland, Stanislaus Augustus.

After partitions of Poland, there was over a century gap in diplomatic relations.

The mission was re-established following Poland regaining independence in the aftermath of World War I.
