Macmillan Publishers of the UK founded St. Martin's Press in 1952. The company took its name from a London street called St Martin's Lane where Macmillan had been headquartered before selling its US stake in 1951.
Holtzbrinck Publishers acquired Macmillan in 1995. Verlagsgruppe Georg von Holtzbrinck, a family-owned concern based in Stuttgart, Germany, controls this group and expanded its reach into English-language publishing through these purchases.
The publisher brings out approximately 700 titles annually across Minotaur, Castle Point Books, St. Martin's Essentials, Wednesday Books, St. Martin's Griffin, and the main imprint itself. Each division handles specific genres ranging from mystery to young adult fiction and mainstream trade paperbacks.
Mary Kay Andrews writes for the company alongside Casey McQuiston while Bill O'Reilly and C. J. Box contribute to their catalog. Kristin Hannah, Nora Roberts, Louise Penny, Rainbow Rowell, Ian K. Smith, Sally Hepworth, Ben Coes, N. Leigh Dunlap, and Jocko Willink also write for the press.
St. Martin's Press became the first major trade-book publisher to release hardcover books through its own mass-market paperback division in 1984. This decision created St. Martin's Mass Market Paperback Co., Inc. and allowed them to control distribution channels more directly.
October 2023 saw social media posts by a St. Martin's Press employee regarding the Gaza war draw attention from the online book community. A Palestinian BookTok member posted screenshots showing anti-Palestine remarks made by that employee which led to the formation of Readers for Accountability as a response.
