Harry Bouton Blackstone Jr. (June 30, 1934 – May 14, 1997) was an American stage magician, author, and television performer.

[3] In his performances, Blackstone used several of his father's tricks and illusions, including the "floating light bulb", "sawing a woman in half", and the "dancing handkerchief".

[4]: 149  His wife, Gay Blackstone, was his magician's assistant, keeping his performances running smoothly onstage and offstage.

They included The Joker cutting Batgirl up into multiple pieces, a variation of a classic multi-box illusion, and the first use in many years of the Jarrett pedestal to vanish Wonder Woman.

He also did special effects for Alice Cooper, Michael Jackson ("The Victory Tour"), Earth, Wind and Fire, and Jane's Addiction with Perry Farrell.

[1] After his death, much of his performance equipment was sold off in two highly publicized auctions held by Sotheby's and Darien Julian.

David Copperfield houses the Tire Vanish (performed by Harry Blackstone Sr.) in his museum of magic.
