The Girl Scouts of the United States of America (GSUSA) is a youth organization for girls in the United States and American girls living abroad. The Girl Scout program, which developed from the concerns of the progressive movement in the United States, sought to promote the social welfare of young ladies and was formed as a counterpart to the Boy Scouts of America (BSA). It was founded by Juliette Gordon Low in 1912 and is based on the Scouting principles developed by Robert Baden-Powell.
The GSUSA uses the Scout method to build self-esteem and to teach values such as honesty, fairness, courage, compassion, character, sisterhood, confidence, and citizenship through activities including camping, community service, learning first aid, and earning numerous badges by acquiring other practical skills. Girl Scouts' achievements are recognized through rank advancement and by various special awards. GSUSA has programs for girls with special interests, such as water-based activities.
Membership is organized according to age group with activities designed appropriately for each level. The GSUSA is a member of the World Association of Girl Guides and Girl Scouts (WAGGGS), and has a long history of accepting girls from all backgrounds.
女童军与男童军是由同一创始人贝登堡发起的兄妹组织.1912年由朱莉亚特·歌顿引入美国。目前世界女童军协会有一百四十多成员国。有约四百万会员的美国女童军是其中最大的成员组织，也是世界上最大的服务女孩的组织。
美国女童军总部设于纽约市，全美有三百多分会，四百万会员中近四分之一是18岁以上的成人义工，其余是5岁至17岁的女孩会员。组织形式也与男童军类似，采取由志愿义工领导的小分队活动。美国人坚信培养男孩和女孩的方法和教育内容不同，因此男女童军组织一直分离组织各自为政，但也有很多合作活动。女童军无疑要针对女孩特点安排内容，近百年来对为美国女性争取权益、培养适合新时代需要的女性作出很大贡献。
目前美国女童军的级别有：
幼女童军(Daisy): 5岁或幼儿班
小女童军(Browney): 6-8岁或1-3年级
少女童军(Junior): 8-11岁或3-6年级
中女童军(Cadette): 11-14岁或6-8年级
资深女童军(Senior): 14-17岁或9-12年级
Studio2B: 近年为11-17岁少女创立的新项目
成人会员：18岁以上男女成人都可以加入作为成人会员担当义工。
