The Schiller Institute is a German-based political and economic think tank founded in 1984 by Helga Zepp-LaRouche, with stated members in 50 countries. It is among the principal front organizations of the LaRouche movement. The institute's stated aim is to apply the ideas of the poet and philosopher Friedrich Schiller to what it calls the "contemporary world crisis." The Independent describes it as "an extremist political think-tank linked to a right-wing conspiracy theorist, Lyndon LaRouche." According to The Times, its aim is "to propagate [LaRouche's] increasingly wild anti-Semitic conspiracy theories."

Helga Zepp-LaRouche is a German political activist. She is the widow of American political activist Lyndon LaRouche, and the founder of the LaRouche movement's Schiller Institute, as well as the German Bürgerrechtsbewegung Solidarität party (BüSo).
