The Colorado Kid is a mystery novel by American writer Stephen King, published by the Hard Case Crime imprint in 2005. The book was initially issued in one paperback-only edition by the specialty crime and mystery publishing house. King's next novel for Hard Case Crime was Joyland, which was published in June 2013. Hard Case Crime reissued The Colorado Kid in an illustrated paperback edition in May 2019.
The third-person narrative concerns the investigation of the body of an unidentified man found on a tiny island off the coast of Maine. Lacking any identification or obvious clues, the case reaches nothing but repeated dead ends. Over a year later the man is identified, but all further important questions remain unanswered. The two-person staff of the island newspaper maintain a longstanding fascination with the case, and twenty-five years later use the mysterious tale to ply the friendship and test the investigative mettle of a post-graduate intern rookie reporter.
A television series loosely inspired by The Colorado Kid, titled Haven, aired on Syfy from July 2010 to December 2015.
