Robert R. McCammon (born July 17, 1952) is an American novelist from Birmingham, Alabama. His parents are Jack, a musician, and Barbara Bundy McCammon. After his parents' divorce, McCammon lived with his grandparents in Birmingham. He received a B.A. in Journalism from the University of Alabama in 1974. McCammon currently resides in Birmingham, and is married to Sally Sanders. The two have a daughter, Skye. McCammon retired from publishing in the late 1990s, but returned to publish Speaks the Nightbird, the first book in the Matthew Corbett Series. , his plans are to continue with the series.

McCammon now refuses to let his first four novels be republished because, while he does not dislike the books, he does not feel that they are up to the standards of his later works. He wrote that he feels he was allowed to learn how to write in public, and therefore has decided to officially retire his earlier works.
