The Dice Man is a 1971 novel by American novelist George Cockcroft, writing under the pen name "Luke Rhinehart".

[3][4][5][6] At the time of its publication, "[i]t was not clear whether the book was fiction or autobiography", all the more because the protagonist and the alleged author were eponymous; both were described as having the same profession (psychiatry), and elements of the described lives of both (e.g., places of residence, date of birth) were also in common;[1][2] hence, curiosity over its authorship have persisted since its publication.

[1][2] Years later, in 1999, Emmanuel Carrère, writing for The Guardian, presented a long-form expose on Cockroft and the relationship between author and legend, disclosing him as a life-long English professor living "in an old farmhouse with a yard that slopes down to a duck pond", a husband of fifty-years, father of three, and a caregiver to a special-needs child.

[7][6] Writing in 2017 for The Guardian, Tanya Gold noted that "over the course of 45 years" it was still in print, had become famous, had devoted fans, and had "sold more than 2m copies in multiple languages".

Manic Street Preachers guitarist and lyricist Richey Edwards cited The Dice Man as one of his favourite novels,[11] and the band referenced Rhinehart in the lyric to their song "Patrick Bateman".
