MASH: A Novel About Three Army Doctors is a 1968 novel by Richard Hooker (the pen name for former military surgeon H. Richard Hornberger and writer W. C. Heinz) which is notable as the inspiration for the feature film M*A*S*H (1970) and the TV series of the same name (1972–1983). The novel is about a fictional U.S. Mobile Army Surgical Hospital in Korea during the Korean War. Hooker followed the novel with two sequels. Additionally, a series of sequels of rather different and lighter tone were credited to Hooker and William E. Butterworth, but actually written by Butterworth alone.
