The fifth edition of OSFair will be held from 15th to 17th September 2025 at the CERN Science Gateway in Geneva, Switzerland, hosted by the CERN Open Science Office and co-organised with OpenAIRE.

This year’s Open Science Fair will explore how diverse forms of collaboration can accelerate discovery, enhance knowledge accessibility, and create a more transparent and equitable research ecosystem. By fostering open and inclusive cooperation across continents, we can build a stronger, more connected scientific community.

The OS FAIR welcomes all actors of the research communities and infrastructures, including: librarians, repository managers, content providers, service providers, research administrators, facilitators of research, learned societies, publishers, policy makers and funders, citizen science groups and initiatives, and innovators in scholarly communication.
