Founded in 1920, The English-Speaking Union of the United States is a 501 (c) (3) non-profit, non-political charitable corporation with the mission to celebrate English as a shared language to foster global understanding and good will by providing educational and cultural opportunities for students, educators, and members.

Headquartered in New York City and incorporated in the State of Delaware, the ESU undertakes its programs through its members in a network of 70 Branches in as many communities nationwide.  An independent American corporation, the ESU-US works in fellowship with more than 50 independent ESUs around the world.

ESU members work together locally, nationally and internationally to foster global understanding through a variety of educational, cultural and social programs.  The ESU's national programs are supported by its unrestricted endowment and corporate and foundation grants as well as by the generosity of its members.  Members benefit from the personal relationships and international exposure gained from ESU activities and events while they provide financial and volunteer support to sustain these programs.
