The National Society of the Daughters of the American Revolution (DAR) is an organization of women directly descended from persons who aided in establishing American independence. Women 18 years of age or over who can prove such descent are eligible for membership. A chief goal of the DAR is to teach and promote good citizenship among youths, adults, and immigrants. Its programs promote appreciation of the past, patriotic service in the present, and educational training for the future. The DAR helps preserve shrines that keep alive the memory of persons who won American independence. It encourages the study of American history, and maintains relics and records of early america.

The organization supports two schools in remote mountain areas of Alabama and South Carolina that are cut off from regular school systems. It also aids six other schools and colleges. It publishes the DAR Manual for Citizenship to help foreign-born residents of the United States in becoming citizens. The DAR sponsors Junior American Citizens Clubs for school children, provides scholarships for American Indians, and runs an annual DAR Good Citizens contest in U.S. high schools. The organization's official publication is The Daughters of the American Revolution Magazine.
