The Boy Scouts of America (BSA) is one of the largest youth organizations in the United States, with over 4.5 million youth members in its age-related divisions. Since its founding in 1910 as part of the international Scout Movement, more than 110 million Americans have been members of the BSA.

The BSA goal is to train youth in responsible citizenship, character development, and self-reliance through participation in a wide range of outdoor activities, educational programs, and, at older age levels, career-oriented programs in partnership with community organizations. For younger members, the Scout method is part of the program to inculcate typical Scouting values such as trustworthiness, good citizenship, and outdoors skills, through a variety of activities such as camping, aquatics, and hiking.

The Boy Scouts of America celebrated its one-hundredth anniversary on February 8, 2010.
