Young European Federalists (JEF Europe) is a political youth NGO that advocates for the creation of a democratic European federation, ensuring peace, the rule of law, and human rights. With over 10,000 activists in 33 countries, JEF Europe promotes true European citizenship, works towards the deepening and widening of the European Union, and strives for a more just and integrated society across the continent. The organization was established in 1972 and is organized into national, regional, and local sections.

At JEF Europe, federalists believe in the power of Europeans working together as one community to achieve long-term peace and prosperity. They reject the concept of a centralized European super-state and promote a federal model based on subsidiarity. JEF Europe tackles issues such as environmental protection, economic stability, migration flows, and fundamental rights and freedoms through political advocacy, projects, and communication activities.

They engage in awareness-raising campaigns, collaborate with organizations and institutions, provide training courses and seminars, and foster contacts between young Europeans. JEF Europe envisions a Europe that is simply a generation ahead, completing the integration process and addressing the challenges of the 21st century to create a more peaceful and sustainable global order
