Will we see you again next year?

Utrecht Science Week 2026 has come to a close. For over a week, visitors enjoyed workshops, lectures, group discussions, and tours focused on science and innovation at Utrecht Science Park. With more than thirty program activities across over 25 locations, there were plenty of opportunities to experience science up close. We look back on a fantastic week that once again highlighted the essential role of collaboration—and the combination of research, education, and entrepreneurship—in addressing today’s societal challenges.

Will we see you again next year? The date for the 2027 edition will be announced soon.

For inspiration, take a look at the program from the recent edition.
