The International Paneuropean Union, also referred to as the Pan-European Movement and the Pan-Europa Movement, is an international organisation and the oldest European unification movement. It began with the publishing of Richard von Coudenhove-Kalergi's manifesto Paneuropa (1923), which presented the idea of a unified European State. The Union's General Secretariat is located in Munich, but maintains branches across Europe.
Since February 2025, the President of the Union is Pavo Barišić, while Alain Terrenoire serves as the Honorary President. The current vice president is Walburga Habsburg Douglas, a former member of the Swedish Parliament.
