Guy Montag is the protagonist and fireman who presents the dystopia through the eyes of a worker loyal to it, a man in conflict about it, and one resolved to be free of it. Through most of the book, Montag lacks knowledge and believes what he hears.
Clarisse McClellan walks with Montag on his trips home and is one month short of being a 17-year-old girl.
Mildred "Millie" Montag is Guy Montag's wife. She is addicted to sleeping pills, absorbed in the shallow dramas played on her "parlor walls" (flat-panel televisions), and indifferent to the oppressive society around her.
Captain Beatty is Montag's boss. Once an avid reader, he has come to hate books due to their unpleasant content and contradicting facts and opinions.
Faber is a former English professor. He has spent years regretting that he did not defend books when he saw the moves to ban them.
