King is the son of authors Stephen and Tabitha King. He was born in Hermon, Maine and grew up in Bangor, Maine.

Hill chose to use an abbreviated form of his given name (a reference to executed labor leader Joe Hill, for whom he was named) in 1997, out of a desire to succeed based solely on his own merits rather than as the son of Stephen King, one of the world’s best-selling and most-recognized living novelists. After achieving a degree of independent success, Hill publicly confirmed his identity in 2007 after an article the previous year in Variety broke his cover (although online speculation about Hill’s family background had been appearing since 2005).
