The Royal Medical and Chirurgical Society of London (RMCS), created in 1805 as the Medical and Chirurgical Society of London, was a learned society of physicians and surgeons, that received a Royal charter in 1834, and a supplement charter in 1907 to create the newly merged Royal Society of Medicine.

The RMCS was founded in 1805 as the Medical and Chirurgical Society of London, by 26 medical men who left the Medical Society of London (founded 1773) in reaction to the autocratic style of its president, James Sims. Among its founders there were William Saunders (1743–1817), its first president; John Yelloly (1774–1842), Sir Astley Cooper (1768–1841), the first treasurer; Alexander Marcet (1770–1822) and Peter Mark Roget (1779–1869).
