Manuel "Mannie" Garcia O'Kelly-Davis is a native-born, slightly cynical inhabitant of Luna who, after losing his lower left arm in a laser-drilling accident, became a computer technician.
Wyoming "Wyoh" Knott-Davis is a political agitator from the colony of Hong Kong Luna. She hates the callous and indifferent Lunar Authority for personal reasons: when she was transported to Luna as a young girl along with her convict mother, a radiation storm contaminated her ova, causing her to later give birth to a deformed child– a misfortune that could have been averted had the Lunar Authority acted in a timely manner to move their ship's passengers from the surface of Luna.
Professor Bernardo de la Paz is an intellectual and lifelong subversive shipped to Luna from Lima, Peru. He describes himself as a "Rational Anarchist", believing that governments and institutions exist only as the actions of aware individuals. Brian Doherty claims that the professor was modeled after autarchist Robert LeFevre.
Mike , alias 'Adam Selene', alias 'Simon Jester', alias 'Mycroft Holmes', officially an augmented HOLMES IV system, is a supercomputer empowered to take control of Lunar society, who achieved self-awareness when his complement of "neuristors" exceeded the number of neurons in the human brain.
Stuart Rene "Stu" LaJoie-Davis , a self-styled "Poet, Traveler, Soldier of Fortune", is an Earth-born aristocrat and tourist rescued by Mannie when he falls afoul of Loonie customs. He later joins Mannie and Professor de la Paz when they return to Luna.
Hazel Meade , later Hazel Stone, is a 12-year-old girl who intervenes on behalf of Mannie and Wyoh during the raid on the agitators' meeting. Mannie later has Hazel join his cabal to lead the children as lookouts and couriers. She is a major character in The Rolling Stones and in later Heinlein novels, most notably The Cat Who Walks Through Walls .
Mimi "Mum" Davis is Mannie's "senior wife" and de facto matriarch of the Davis family.
Greg Davis is the Davis family's second ranking husband, but is the senior for all practical purposes as "Grandpaw Davis" has failing mental faculties. Greg is a preacher for an unspecified denomination.
