"Johnny Mnemonic" is a science fiction short story by American-Canadian writer William Gibson. It first appeared in Omni magazine in May 1981, and was subsequently included in Burning Chrome, a 1986 collection of Gibson's short fiction. It takes place in the world of Gibson's cyberpunk novels, predating them by some years, and introduces the character Molly Millions, who plays a prominent role in the Sprawl trilogy of novels. The short story served as the basis for the 1995 film Johnny Mnemonic, whose plot uses the same basic premise but otherwise differs considerably. A novelization of Gibson's screenplay written by Terry Bisson was published in 1995. In 1996 a film tie-in edition of Gibson's original short story was published as a standalone book.

To add to his troubles, Johnny has learned that Ralfi has placed a contract on him, although the reasons are unclear. Johnny finds Ralfi at his usual table, accompanied by his bodyguard Lewis. Johnny threatens them with a sawed-off shotgun in his bag, but Lewis incapacitates him with a neural disruption device hidden under the table. Ralfi reveals that the data was, unknown to him at the time, stolen from the Yakuza, who are very interested in ensuring it is not revealed. Johnny is rescued by Molly, a "razorgirl" who has undergone extensive body modifications, most notably razor-sharp blades under her fingernails. She joins the three men at their table, looking for a job. When Lewis tries to attack her, she cuts his wrist tendons and takes the incapacitating control device from him. Ralfi offers to
