Stephen Edwin King was born on September 21, 1947, at the Maine General Hospital in Portland. His parents were Nellie Ruth (Pillsbury), who worked as a caregiver at a mental institute, and Donald Edwin King, a merchant seaman. His father was born under the surname "Pollock", but used the last name "King", under which Stephen was born. He has an older brother, David. The Kings were a typical family until one night, when Donald said he was stepping out for cigarettes and was never heard from again. Ruth took over raising the family with help from relatives. They traveled throughout many states over several years, finally moving back to Durham, Maine, in 1958.
