Europäische Akademie Otzenhausen EAO, Political education center in Otzenhausen, Nonnweiler, Germany

The Europäische Akademie Otzenhausen is a non-governmental political-education and meeting centre in Otzenhausen, part of Nonnweiler in northern Saarland, founded in 1954. Its conference centre has 17 flexible seminar and group rooms, four with simultaneous interpreting booths for up to five languages, a restaurant and 108 beds in 67 rooms. It sits in the SaarLorLux region within the Hunsrück-Hochwald National Park, near the Celtic ring wall and the Nonnweiler reservoir.

Founded in 1954 by Arno Krause, the academy evolved into an important meeting point for international gatherings and debates about Europe. Over the decades, it became established as a center for political education and academic exchange.

The academy's guiding phrase is "Europa entsteht durch Begegnung" (Europe comes about through encounter). Its founder and long-time director was Arno Krause (1930–2018). It added the Institut für Rhetorik und Methodik in 1968, the institute now called IGR – Institut der Großregion in 1971, and ran the Sozialwissenschaftliches Forschungsinstitut from 1991 to 2005, then a leading centre of interdisciplinary GDR research.

The academy sits in the Saarland part of the Hunsrück-Hochwald National Park, in the SaarLorLux region, near Luxembourg, Strasbourg and Brussels. The Nonnweiler dam can be reached on foot, and the Bostalsee is a few minutes away by car. The Celtic ring wall and Keltenpark lie directly nearby.

The academy has hosted the secretariat of the Fédération internationale des Maisons de l'Europe (FIME) from 1972 to 2005, as a founding member. Its campus lies in the Saarland part of the Hunsrück-Hochwald National Park, within the SaarLorLux region, near the Celtic ring wall of Otzenhausen and the Nonnweiler reservoir, which can be reached on foot.
