The Girl Guides (later renamed the Girl Scouts of the USA) are founded in the United States.

Girl Guides are organisations within the Scout Movement originally and largely still for girls and women only. The Girl Guides began in 1910 with the formation of The Girl Guides Association in the United Kingdom, following which, similar girl-only organisations were formed in other countries. Many girls and some organisations preferred to use the name Girl Scouts.

Girl Scouts of the United States of America (GSUSA), commonly referred to as Girl Scouts, is a youth organization for girls in the United States and American girls living abroad. It was founded by Juliette Gordon Low in 1912, a year after she had met Robert Baden-Powell, the founder of Scouting.

The United States of America (USA), also known as the United States (U.S.) or America, is a country primarily located in North America. It is a federal republic of 50 states and a federal capital district, Washington, D.C. The 48 contiguous states border Canada to the north and Mexico to the south, with the semi-exclave of Alaska in the northwest and the archipelago of Hawaii in the Pacific Ocean. The United States also asserts sovereignty over five major island territories and various uninhabited islands in Oceania and the Caribbean. It is a megadiverse country, with the world's third-largest land area and third-largest population, exceeding 340 million.
