The Copley Medal is a scientific award for work in any field of science, the highest award granted by the Royal Society of London. It is also the society's oldest award, the first medal being awarded in 1731.

The award was created after a £100 bequest in 1709 to the Royal Society by Sir Godfrey Copley, a wealthy landowner from Sprotbrough, near Doncaster, South Yorkshire, who was elected to the Society in 1691.

It is one of ten medals that the Society awards (some awards are made annually, others at different intervals according to their terms of reference). The Copley Medal alternates between the physical sciences and the biological sciences, and the winners are selected by Fellows of the Society.
