Joshua Hampton is a 6-month-old infant in Grand Theft Auto IV. The Hampton family lived in an apartment in Rotterdam Hill. Hampton is accused of killing his father Abraham Hampton to marry his mother. He was arrested by police but posted bail and fled town with his newly married wife. He allegedly murdered his father because of "misuse of the milk-machines" (referring to his mother's breasts). It was also stated that he was going to marry his mother in Vice City because strange behavior is tolerated there.
- Joshua is a possible reference to Oedipus, a tragical hero in Greek mythology, who kills his father and marries his mother.
