Charles "Kid" McCoy, original name Norman Selby (October 13, 1872 - April 18, 1940) was a world champion boxer.

It is thought that the expression "the real McCoy" originally referred to him.

He died from an overdose of sleeping pills. His suicide note read, among other things: "Everything in my possession, I want to go to my dear wife, Sue E. Selby... To all my dear friends...best of luck...sorry I could not endure this world's madness."
