The Hospital for Sick Children (HSC), corporately branded as SickKids, is a major pediatric teaching hospital located on University Avenue in Toronto, Ontario, Canada. Affiliated with the Faculty of Medicine of the University of Toronto, the hospital was ranked the top pediatric hospital in the world by Newsweek in 2021.

A children's hospital (CH) is a hospital that offers its services exclusively to infants, children, adolescents, and young adults from birth up to until age 18, and through age 21 and older in the United States. In certain special cases, they may also treat adults. The number of children's hospitals proliferated in the 20th century, as pediatric medical and surgical specialties separated from internal medicine and adult surgical specialties.
