The Harvey Club of London is the oldest currently active medical club in Canada. It was founded by Drs. James W. Crane and C.M. Crawford in 1919 in London, Ontario. The club was initially founded as a way for practicing physicians to stay abreast of new developments in biomedical sciences, analogous to the modern concept of continuing medical education, a function that it continues to perform with annual presentations of papers. The club also provides academic and financial support to students at the medical school of Western University.

William Harvey was an English physician who made influential contributions in anatomy and physiology. He was the first known physician to describe completely, and in detail, the systemic circulation and properties of blood being pumped to the brain and the rest of the body by the heart, though earlier writers, such as Realdo Colombo, Michael Servetus, and Jacques Dubois, had provided precursors of the theory.
