The Spanish Esperanto Federation (Federación Española de Esperanto) is an association dedicated to promoting the Esperanto language and supporting its community in Spain. Its website provides information about Esperanto, including its history, origins, use in Spain and wider culture, alongside answers to common questions and educational resources. People interested in learning can find information about online and in-person courses, self-study options and other learning materials.

The federation also connects speakers through local groups, associations, meetings and events, including regional and national congresses. Its resources highlight Esperanto literature, magazines, music, radio, film, academic work, libraries and online communities, as well as opportunities to travel and communicate across borders. Visitors can explore news, media coverage, an events calendar, a daily word, an online dictionary and digital library collections. The federation offers publications and book sales, information about membership and volunteering, and ways to collaborate with the association. Based in Madrid, it also shares information about international and Ibero-American activities and represents Spanish Esperanto speakers within the broader international Esperanto community.
