Flags of the U.S. states and territories

The flags of the U.S. states, territories and federal district exhibit a variety of regional influences and local histories, as well as different styles and design principles. Nonetheless, the majority of the states' flags share the same design pattern consisting of the state seal superimposed on a monochrome background, commonly blue.

The most recent current state flag is that of Minnesota (May 11, 2024), while the most recent current territorial flag is that of the Northern Mariana Islands (July 1, 1985).
