The Boy Scouts of America is incorporated by William D. Boyce.

William Dickson Boyce (June 16, 1858 June 11, 1929) was an American newspaper man, entrepreneur, magazine publisher, and explorer. He was the founder of the Boy Scouts of America (BSA) and the short-lived Lone Scouts of America (LSA). Born in Allegheny County, Pennsylvania, he acquired a love for the outdoors early in his life. After working as a schoolteacher and a coal miner, Boyce attended Wooster Academy in Ohio before moving to the Midwest and Canada. An astute businessman, Boyce successfully established several newspapers, such as The Commercial in Winnipeg, Manitoba and the Lisbon Clipper in Lisbon, North Dakota. With his first wife, Mary Jane Beacom, he moved to Chicago to pursue his entrepreneurial ambitions. There he established the Mutual Newspaper Publishing Company and the weekly Saturday Blade, which catered to a rural audience and was distributed by thousands of newspaper boys. With his novel employment of newsboys to boost newspaper sales, Boyce's namesake publishing company maintained a circulation of 500,000 copies per week by 1894. Boyce strongly supported worker rights, as demonstrated by his businesses' support of labor unions and his concern for his newsboys' well-being.

By the early years of the 20th century, Boyce had become a multi-millionaire and had taken a step back from his businesses to pursue his interests in civic affairs, devoting more time to traveling and participating in expeditions. In 1909, he embarked on a two-month trip to Europe and a large photographic expedition to Africa with photographer George R. Lawrence and cartoonist John T. McCutcheon. Over the next two decades, Boyce led expeditions to South America, Europe, and North Africa, where he visited the newly discovered tomb of King Tutankhamun.

Boyce learned about Scouting while passing through London during his first expedition to Africa in 1909. According to somewhat fictionalized legend, Boyce had become lost in the dense London fog, but was guided back to his destination by a young boy, who told him that he was merely doing his duty as a Boy Scout. Boyce then read printed material on Scouting, and on his return to the United States, he formed the B.S.A.

From its start, Boyce focused the Scouting program on teaching self-reliance, citizenship, resourcefulness, patriotism, obedience, cheerfulness, courage, and courtesy in order "to make men". After clashing over the Scouting program with the first Chief Scout Executive James E. West, he left the B.S.A. and founded the L.S.A. in January 1915, which catered to rural boys who had limited opportunities to form a troop or a patrol.

In June 1924, five years before Boyce's death, a merger was completed between the B.S.A. and the struggling L.S.A. Boyce received many awards and memorials for his efforts in the U.S. Scouting movement, including the famed "Silver Buffalo Award".

The Boy Scouts of America (BSA, colloquially the Boy Scouts) is one of the largest scouting organizations and one of the largest youth organizations in the United States, with about 1.2 million youth participants. The BSA was founded in 1910, and since then, about 110 million Americans have participated in BSA programs. BSA is part of the international Scout Movement and became a founding member organization of the World Organization of the Scout Movement in 1922.

The stated mission of the Boy Scouts of America is to "prepare young people to make ethical and moral choices over their lifetimes by instilling in them the values of the Scout Oath and Law." Youth are trained 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 instill typical Scouting values such as trustworthiness, good citizenship, and outdoors skills, through a variety of activities such as camping, aquatics, and hiking. To further these outdoor activities, the BSA has four high-adventure bases: Northern Tier (Minnesota, Manitoba, and Ontario), Philmont Scout Ranch (New Mexico), Sea Base (Florida, US Virgin Islands, and Bahamas), and Summit Bechtel Reserve (West Virginia), as well as nearly one hundred separate camps and reservations specifically dedicated to scouts.

The main Scouting divisions are Cub Scouting for ages 5 to 11 years, Scouts BSA for ages 10 to 18, Venturing for ages 14 through 21, and Sea Scouts for ages 14 through 21. The BSA operates Scouting by chartering local organizations, such as churches, clubs, civic associations, or educational organization, to implement the Scouting program for youth within their communities. Units are led entirely by volunteers appointed by the chartering organization, who are supported by local councils using both paid professional Scouters and volunteers. Additionally, Learning for Life is an affiliate that provides in-school and career education.

On February 1, 2019, the Boy Scouts of America renamed its flagship program, Boy Scouts, to Scouts BSA to reflect its policy change allowing girls to join separate, gender-specific troops. Shortly thereafter, the largest charter organization supporting BSA, The Church of Jesus Christ of Latter-day Saints, decided to part ways substantially contributing to a net loss of nearly a million scouts/leaders. On February 18, 2020, the National BSA filed for Chapter 11 bankruptcy protection and is currently restructuring its financial situation. On November 16, 2020, the National BSA disclosed in their bankruptcy filings that over 92,000 former Scouts had reported sexual abuse by members of the organization. In December of 2021, the insurer for the Boy Scouts of America agreed to pay $800M into the fund for victims.
