Lyle Stuart (born Lionel Simon; August 11, 1922 – June 24, 2006) was an American author and independent publisher of controversial books.

Stuart had first gained national notoriety by taking on the powerful newspaper columnist Walter Winchell in a series of scathing magazine articles, collected in book form in 1953.

After serving with the United States Merchant Marine and the Air Transport Command in World War II, he worked for William Randolph Hearst's International News Service, Variety, Music Business, and RTW Scout.

In the early 1980s, Lyle Stuart Inc. made a deal with UK publishers Target Books/W H Allen for US distribution of the paperback novelizations of the TV series Doctor Who, coinciding with the increasing popularity of the show on US public broadcasting.

[4] In 1997, Stuart's publishing house Barricade Books reissued The Turner Diaries, a novel thought to have been the inspiration behind Timothy McVeigh's bombing of the Murrah building.

The copy on Running Scared, a biography of Wynn, made reference to a New Scotland Yard report that tied the Las Vegas tycoon to the Genovese Crime Family.
