Croucher Science Week is an annual science festival held every spring in Hong Kong. It is produced by the Croucher Foundation, an independent private foundation established by the late Noel Croucher in 1979 to promote the standard of natural sciences, technology and medicine in Hong Kong. Since its launch in 2018 the event has inspired thousands of students and children.

The mission of Croucher Science Week is to raise science literacy within society and bridging the gap between scientists and the younger generation. Science plays a fundamental role in our lives. We believe everyone deserves to be inspired by science and that science education should be made available to all. We hope to nurture scientific curiosity and make science relevant in the daily lives of our younger generation.

Each year, Croucher Science Week gathers some of the greatest minds in science from around the world to share their scientific discoveries through activities including science shows, interactive explorations, talks, and workshops tailored for the Hong Kong audience. Past participants include the Australian Museum from Australia, Nanogirl from New Zealand, the Royal Institution from the UK, and Steve Spangler from the US.

Croucher Science Week also invites Croucher Scholars (Croucher award recipients), a group of brilliant Hong Kong scientists who are undertaking cutting-edge research and undertaking innovative projects, to share their enthusiasm for science with local audiences.

Croucher Science Week is funded by the Croucher Foundation, and is jointly organised by the Croucher Foundation, the HKSAR Education Bureau, and the Hong Kong Science Museum (managed by the Leisure and Cultural Services Department of the HKSAR).
