Captain Charles Johnson was the British author of the 1724 book A General History of the Robberies and Murders of the most notorious Pyrates, whose identity remains a mystery. No record exists of a captain by this name, and "Captain Charles Johnson" is generally considered a pen name for one of London's writer-publishers. Some scholars have suggested that the author was actually Daniel Defoe, but this is disputed.

A General History of the Robberies and Murders of the most notorious Pyrates, or simply A General History of the Pyrates, is a 1724 book published in Britain containing biographies of contemporary pirates, which was influential in shaping popular conceptions of pirates. Its author uses the name Captain Charles Johnson, generally considered a pen name for one of London's writer-publishers. The prime source for the biographies of many well-known pirates, the book gives an almost mythical status to the more colourful characters, and it is likely that the author used considerable artistic license in his accounts of pirate conversations. The book also contains the name of Jolly Roger, the pirate flag, and shows the skull and crossbones design.
