The flags of the U.S.states, territories, and the District of Columbia (Washington, D.C.) exhibit a variety of regional influences and local histories, as well as different styles and design principles. Modern U.S. state flags date from the turn of the 20th century, when states considered distinctive symbols for the 1893 World's Columbian Exposition in Chicago, Illinois. Most U.S. state flags were designed and adopted between 1893 and World War I.[1]
The most recently adopted state flag is that of Minnesota, adopted on May 11, 2024, while the most recently adopted territorial flag is that of the Northern Mariana Islands, adopted on July 1, 1985. The flag of the District of Columbia was adopted in 1938. Recent legislations in Massachusetts (2021) and Illinois (2024) have started the process of redesigning their state flag. Maine and Michigan also have plans to redesign their flags in the future, but these have not been confirmed, though Maine has planned to put a flag redesign on the ballot in November of 2024.[2]
Despite a variety of designs, the majority of the states' flags share the same design pattern consisting of the state seal superimposed on a monochrome
background, commonly a shade of blue, which remains a source of criticism from vexillologists. According to a 2001 survey by the North American Vexillological Association, New Mexico has the best-designed flag of any U.S. state, U.S. territory, or Canadian province, while Georgia's state flag was rated the worst (the latter of which has been changed since the survey was conducted).[3]

Many Native American nations have tribal sovereignty, with jurisdiction over their members and reserved land. Although reservations are on state land, the laws of the state(s) do not necessarily apply.[25] Below are the flags of some of the largest Indian tribes reservations by population and area:
The U.S. national flag is the official flag for all islands, atolls, and reefs composing the United States Minor Outlying Islands. However, unofficial flags are sometimes used to represent some of these insular areas:
