The Ontario Science Centre (OSC), originally the Centennial Museum of Science and Technology, is a science museum and educational organization based in Toronto, Ontario, Canada. Founded during Canada's centennial era, the OSC became known for its interactive exhibits, hands-on programming, and a facility intended to "integrate architecture with the surrounding landscape".

As of the mid 2020s, the centre has become the subject of public debate after the Ontario government announced plans to relocate the institution and move its main facilities elsewhere. The subsequent closure of the original site and the opening of temporary exhibit spaces elsewhere in Toronto prompted political scrutiny and professional criticism.

Construction has started for the Centre's relocation into Ontario Place, forecasting a 2029 opening.
