Celebrating Europe together, on the ground!

Interreg Cooperation Day is your invitation to show citizens what happens when regions work together. Every year, Interreg programmes and partners host public events across Europe, turning European cooperation into something real, local and human.

Who makes it all happen?

Interreg programmes and partners across the continent take the lead in organising events that bring cooperation to life. To make that easier, Interact steps in with tools, materials and this very website, all designed to support local teams in planning, promoting and sharing their activities.

Official branding

Access to the official Interreg logo and 15th-anniversary branding to ensure consistent visibility in your event.

A series of six overlapping banners marked "Cooperation Day" show images of hands joined, people collaborating, using technology, supporting each other, and scenic landscapes with the EU emblem on each.

Visual identity

Includes themed banners (nature, tech, sports, culture, social media, workshop) and templates for consistent branding.

Promotional video

Interact provides a short video promoting the campaign, with the option to customise it with your event details.

The image shows a creative "15" design with photos inside the numbers, marking an anniversary. "Anniversary" is written in blue, and an orange box reads "Guide for programmes 2026." People are visible in the photo collage.

Guidance

Participation in the Interreg Cooperation Day offers a great opportunity for the programmes to reach out together to the people who are not generally familiar with Interreg.

It is voluntary and, in practice, participation means organising one or more local events or activities. Given the goals of Interreg Cooperation Day, programmes share one belief: the greater number of participating programmes, the more successful the campaign will be.
