Esperanto-USA

Esperanto-USA (E-USA) is the largest organization for speakers and supporters of Esperanto in the United States. It was founded in 1952 as the Esperanto League for North America (ELNA) at the famous "Senator Hotel" in Sacramento, California. Still headquartered in Sacramento today, Esperanto-USA is a 501(c)(3) nonprofit organization and the U.S. affiliate of the Universal Esperanto Association. Brandon Sowers is President of E-USA, and Quintyn Bobb is Vice-President.

The organization administers the largest Esperanto-language book service in the Americas and publishes a quarterly bulletin Usona Esperantisto. It also administers the American Good Film Festival, a short-film contest open to amateur and professional film-makers around the world. In the first six film festivals, Esperanto-USA added more than 150 original Esperanto films to its Youtube channel.

The organization's leadership consists of a paid executive director and a volunteer board including president, vice-president, secretary, treasurer, and nine directors; it also has many commissioners responsible for Esperanto-USA's activity in various connections (e.g. audio-visual service; cooperation with libraries; relations with local Esperanto clubs; etc.). Special interest groups associated with the organization include ham radio, chess, and veganism/vegetarianism.

The youth section of E-USA is USEJ (Usona Esperantista Junularo).
