The Order of the Arrow (OA) is the honor society of the Boy Scouts of America (BSA), composed of Scouts and Scouters who best exemplify the Scout Oath and Law in their daily lives as elected by their peers. The society was created by E. Urner Goodman, with the assistance of Carroll A. Edson, in 1915 as a means of reinforcing the Scout Oath and the Scout Law. It uses imagery commonly associated with American Indian cultures for its self-invented ceremonies. These ceremonies are usually for recognition of leadership qualities, camping skills, and other scouting ideals as exemplified by their elected peers.

Influenced by Scout camp customs, the OA uses "safeguarded" (privy only to members) symbols, handshakes, and private rituals to impart a sense of community. Native Americans have criticized the OA's various symbols and "rituals" as cultural appropriation based on non-Native stereotypes of American Indians.

Inducted members, known as Arrowmen or Brothers, are organized into local youth-led lodges that harbor fellowship, promote camping, and render service to Boy Scout councils and their communities. Each lodge corresponds to a BSA council in the area. Lodges are further broken down into chapters, which correspond to a district in scouting. Members wear identifying insignia on their uniforms, most notably the OA pocket flap that represents their individual OA lodge and the OA sash worn at official OA functions. The OA program sponsors several events, awards, and training functions.
