これはアメリカ合衆国の国旗の一覧で、アメリカ合衆国国旗の変遷、および政府機関の旗など、アメリカ合衆国内で使用されているその他の旗について説明しています。大使館や船舶用の旗も別途存在します。
1818年以降、各州が加盟した翌年の7月4日に、各州の星が国旗に追加されてきました。複数の州が加盟した年には、その数に応じた星が国旗に追加されました。この変更は、1777年以降の国旗の改訂で通常行われた唯一の変更であり、例外として、縞の数がそれぞれ15に増え、その後13に戻された1795年と1818年の変更があります。1912年以前は星の正確な配置が規定されていなかったため、歴史的な米国国旗(下記参照)の多くは、星の配置が異なっています。[ 1 ]

Many agencies, departments, and offices of the U.S. federal government have their own flags, guidons, or standards. Following traditional American vexillology, these usually consist of the agency's departmental seal on a blank opaque background, but not always.

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 every different shade of blue, which remains a source of criticism from vexillologists.
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).
Modern U.S. state flags date from the 1890s, when states wanted to have distinctive symbols at the 1893 World's Columbian Exposition in Chicago, Illinois. Most U.S. state flags were designed and adopted between 1893 and World War I.[3]
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 design.[4] (Georgia adopted a new flag in 2003; Nebraska's state flag, whose design was rated second worst, remains in use to date.)
Dates in parentheses denote when the current flag was adopted by the state's legislature.
