Therefore, the efficiency and productivity of human resources must be enhanced. This study aims to: (1) analyze the influence of personality traits (Neuroticism, Extraversion, Openness to Experience, Agreeableness, Conscientiousness) and interpersonal communication on organizational commitment at the Palopo City Health Office, and (2) identify the dominant variable among these factors that most significantly impacts organizational commitment. The research employs multiple linear regression analysis, supported by descriptive analysis. The findings reveal that: (1) personality traits (neuroticism, extraversion, openness to experience, agreeableness, conscientiousness) and interpersonal communication have a positive and significant effect on organizational commitment; (2) Conscientiousness is the most dominant variable influencing organizational commitment; (3) the coefficient of determination (R²) test result shows a value of 0.735, indicating that the independent variables influence the dependent variable by 73.5%, while the remaining 26.5% is affected by other factors not included in this study; and (4) both the simultaneous and partial tests demonstrate that all independent variables significantly affect the dependent variable, either collectively or individually.Keywords: Personality, Interpersonal Communication, Organizational CommitmentAbstrakSumber daya manusia merupakan salah satu aset penting organisasi, baik di sektor swasta maupun publik, yang berperan signifikan dalam mencapai tujuan organisasi.
