他的文学作品通常以动作类型为基础，并大量采用技术。他的小说是技术惊悚文学类型的缩影，经常探索技术以及人类与之互动的失败，尤其是导致生物技术的灾难。他未来的许多历史小说都有医学或科学基础，反映了他的医学训练和科学背景。他是《侏罗纪公园》、《仙女座菌株》、《刚果》、《游记》、《球体》、《旭日东升》、《披露》、《失落的世界》、《机身》、《时间线》、《猎物》、《恐惧状态》、《下一步》（他去世前出版的最后一本书）、《海盗纬度》（2009 年 11 月 24 日出版）等的作者，以及一部尚未发行的最后一部未完成的技术惊悚片。《福布斯》将克莱顿列为2009年“收入最高的已故名人”名单中的第十位。

John Michael Crichton (October 23, 1942 – November 4, 2008), best known as Michael Crichton, was an American author, producer, director, and screenwriter, best known for his work in the science fiction, medical fiction, and thriller genres. His books have sold over 150 million copies worldwide, and many have been adapted into films. In 1994, Crichton became the only creative artist ever to have works simultaneously charting at #1 in television, film, and book sales (with ER, Jurassic Park, and Disclosure, respectively).

His literary works are usually based on the action genre and heavily feature technology. His novels epitomize the techno-thriller genre of literature, often exploring technology and failures of human interaction with it, especially resulting in catastrophes with biotechnology. Many of his future history novels have medical or scientific underpinnings, reflecting his medical training and science background. He was the author of, among others, Jurassic Park, The Andromeda Strain, Congo, Travels, Sphere, Rising Sun, Disclosure, The Lost World, Airframe, Timeline, Prey, State of Fear, Next (the final book published before his death), Pirate Latitudes (published November 24, 2009), and a final unfinished techno-thriller yet to be released. Forbes listed Crichton in tenth place in its list of "Top-Earning Dead Celebrities" of 2009.
