It makes need very relevant to every human in everyday life. This study discusses about the fulfillment of human needs that is represented through one of the main character in Emma Donoghue’s Room novel named Ma. The aim of this study is to reveal how Ma fulfills her needs based on Henry Murray’s theory of needs. The researcher used qualitative method and psychological approach. Further, the theories used in this analysis are the theory of human needs proposed by Henry Murray and the theory of characterization by M. J. Murphy. The results of this study show that Ma as one of the main characters in the novel, fulfills all types of the needs. Those needs are abasement, achievement, affiliation, aggression, autonomy, counteraction, deference, defendance, dominance, exhibition, harmavoidance, infavoidance, nurturance, order, play, rejection, sentience, sex, succorance, and understanding needs. Meanwhile, the types of needs that Ma experiences the most are affiliation, dominance, nurturance, and sentience needs. On the other hand, the findings show that those representations of the needs are characterized in Ma’s character in speech, reaction, mannerism, and character as seen by others.
