Thomas McCormack (January 5, 1932 – June 15, 2024) was an American book-publishing executive, editor, author, and playwright.
Following a period writing radio news on station WSTC in Stamford, McCormack entered book publishing.
Finally he joined St. Martin's Press and, eleven years after entering publishing, he was appointed the CEO.
His maverick strategy – which included publishing more fiction than any other house in America – helped St. Martin's expand its annual billings from two-and-a-half-million dollars to over a quarter-billion.
In the 1980s he had St. Martin's launch its own mass-market paperback line, the first hardcover house to do that since Simon and Schuster founded Pocket Books in 1939.
Meantime he was editing bestsellers ranging from All Creatures Great and Small to The Silence of the Lambs.
In the late 1990s, after aiding in the sale of St. Martin's to the Holtzbrinck Publishing Group of Germany, McCormack resigned his role as chairman, CEO, and editorial director to pursue his interest in theater.

McCormack's wife, the former Sandra Danenberg, was a celebrated book editor of fiction.
