We cooperate beyond borders to help Europe thrive
What is Interreg
Interreg is a series of EU funding programmes that support cooperation. By bringing together organisations from across Europe and beyond, Interreg tackles shared challenges and creates lasting connections. From boosting economic growth and regional cohesion to protecting the environment and promoting sustainable development, Interreg-funded projects make a real difference in people’s lives. Together, we are building a more united, resilient and prosperous Europe where every region thrives.
