The 5th Open Science Fair (OSFair) Conference will be held from September 15 to 17, 2025, at CERN in Geneva, Switzerland, the global epicenter of scientific discovery and innovation! As the birthplace of groundbreaking research and home to the world’s largest particle physics laboratory, CERN embodies the spirit of collaboration, unity, and the pursuit of knowledge, making it the ideal setting to advance the Open Science movement.

This exciting event, hosted by CERN's Open Science Office and co-organised with OpenAIRE, aims to reconnect a diverse and influential community of researchers, policymakers, publishers, funders, and open science advocates from around the world. Building on the successes of previous years, which have consistently advanced the dialogue and development of open science, OSFair2025 promises to be another landmark event. Join us for three inspiring days dedicated to advancing the frontiers of open science. 

OSFair 2025 Theme: “Fusing Forces – Accelerating Open Science through Collaboration

In an era where global challenges demand collective intelligence, Open Science Fair 2025 will spotlight the power of global, international and cross-regional partnerships in shaping the future of Open Science. True progress requires collaboration that transcends borders, disciplines, and institutions—uniting diverse perspectives to drive meaningful change.

This year’s OSFair 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.

Stay tuned for announcements on more specific topics, speakers, sessions, participation and sponsorship opportunities!
