About

Interreg Cooperation Day

Interreg Cooperation Day is an annual campaign celebrating the power of European cooperation across borders.

Each year, thousands of people take part in cultural events, leisure activities, and sports across the continent, organised by Interreg programmes. From cycling tours to concerts and community gatherings, the campaign highlights the impact of EU-funded cooperation in making regions stronger.

 

Since its launch in 2012, the initiative has grown, with more than 1,490 events organised and a reach of 47 million. The goal is to showcase real results of collaboration through engaging activities that bring communities together. Interreg Cooperation Day is celebrated on 21 September and the surrounding weeks, with plenty opportunities for programmes to join!
