Faithful is a 2004 book co-written by Stephen King and Stewart O'Nan.

It chronicles exchanges between King and O'Nan about the 2004 Boston Red Sox season, beginning with an e-mail in the summer of 2003, and throughout the 2004 season, from spring training to the World Series.

The book was dedicated to Victoria Snelgrove,[1] an Emerson College student who was struck in the eye by the Boston Police Department with a projectile and killed during crowd-control actions near Fenway Park following Game 7 of the American League Championship Series.
