Flame of Hope, Memorial in London, Ontario, Canada.

The Flame of Hope is a stone monument with a gas-fed flame that stands at the entrance to Banting House National Historic Site in downtown London, Ontario, Canada. The monument was placed directly in front of the house where Frederick Banting first developed his ideas about insulin.

The monument was built in 1989 to mark the contribution of Frederick Banting, who began developing his ideas about insulin in this house in the early 1920s. He later continued his research at the University of Toronto, where the first successful tests on humans took place.

The flame's name is used by Diabetes Canada and other groups for fundraising events, including a non-competitive 5 km walk or fun run and golf tournaments in several Canadian cities. A 1996 event marking the 75th anniversary of insulin's discovery saw participants walk from Victoria Park to Banting House, where a judge re-dedicated the flame.

The monument sits right on the sidewalk in front of the house and can be seen from the street at any time of day. The interior of the adjacent historic house is open to visitors and guided tours are available through the on-site museum.

The flame was kindled by Queen Elizabeth the Queen Mother on July 7, 1989, before 4,000 spectators. Within its first year a 26-year-old man smothered it with his jacket, smashing the ignition switches and burners and causing $1,760 in damage; the Queen Mother wrote a letter urging that it be relit, and the monument was rebuilt to a more tamper-proof design.
