Thunder Bay Regional Health Sciences Centre (TBRHSC) was founded in 2004 in Thunder Bay, Ontario. It acts as the major acute care hospital serving people in Thunder Bay and across Northwestern Ontario.

The TBRHSC is known for its cancer research and education practices. The hospital works closely with the Northern Ontario School of Medicine University and the Thunder Bay Regional Health Research Institute. The TBRHSC is listed as one of the “Top 40 Research Hospitals in Canada."

In 1995, Thunder Bay’s McKellar General Hospital (founded in 1903) and Port Arthur General Hospital (founded in 1909) amalgamated to form the Thunder Bay Regional Hospital. This organization evolved into the TBRHSC with a new building, holding its grand opening in 2004. The new build design received awards, such as being rated sixth on the list of “the world's 30 most architecturally impressive hospitals.”
