The Chapman Medal is an award of the Royal Astronomical Society, given for "investigations of outstanding merit in the science of the Sun, space and planetary environments or solar-terrestrial physics". It is named after Sydney Chapman (1888–1970), a British geophysicist who worked on solar-terrestrial physics and aeronomy. The medal was first awarded in 1973, initially on a triennial basis. From 2004 to 2012 it was awarded biennially, and since 2012 has been annual.
