Lyle Kenyon Engel (c.1915 - August 10, 1986) was an American magazine publisher and book producer. Taking over the family business after his father's death, Engel made the company the largest publisher of lyric magazines in the country. He later founded Book Creations, Inc., which became one of the most successful "fiction factories" in the United States, hiring writers to write books to Engel's outlines which he sold to paperback publishers. Engel's most successful series was The Kent Family Chronicles by John Jakes.
