The Flame of Hope is an eternal flame located in London, Ontario, Canada, that honours Sir Frederick Banting's discovery of insulin, as well as all those who have been affected by diabetes. Simultaneously, it serves as a reminder that insulin manages diabetes but does not cure it; ultimately, it stands for the hope that a cure will soon be found.

Sir Frederick Grant Banting was a Canadian pharmacologist, orthopedist, and field surgeon. For his co-discovery of insulin and its therapeutic potential, Banting was awarded the Nobel Prize in Physiology or Medicine with John Macleod.
