John Robert "Johnny" Fox (November 13, 1953 – December 17, 2017) was an American professional sword swallower and sleight of hand expert.

[4][5] At approximately the same age, his father gave him a book about Harry Houdini which inspired Fox—substituting spaghetti—to recreate the magician's trick of swallowing a key on a string and then regurgitating it.

In his early twenties, Fox was performing in Boulder, Colorado, when he heard that his act had been stolen by a competing magician.

Fox appeared at such venues as comedy clubs, casinos, and tattoo conventions, as well as special events such as an Aerosmith album release party.

His collection of oddities includes narwhal tusks, an elephant's-foot liquor chest, a two-headed turtle, a vest owned by General Tom Thumb, and the glass eye of Sammy Davis Jr. Fox married his wife, Valeria, an Argentine dancer and photographer, while they were atop elephants in Annapolis, Maryland, in 2002.

[10] Then, in the winter of 2016, Fox slipped on black ice at his home in Connecticut which, combined with his liver problems, put him in a coma for several days.
