Is it the American flag or US Flag?

Both "American flag" and "U.S. flag" are commonly used to refer to the flag of the United States of America. The term "American flag" emphasizes the flag's association with the United States as a whole, while "U.S. flag" specifically denotes the flag's national affiliation.

The United States Flag Code, which governs the proper use and display of the American flag, officially refers to it as the "flag of the United States of America." However, the code also acknowledges the use of the term "American flag" and provides guidelines for its proper display.
