This study aimed to examine the associations between nurses’ perceptions of ethical leadership, organizational communication climate, and organizational commitment. Methods & Materials: This cross-sectional study was conducted with 265 nurses working at Ödemiş State Hospital in İzmir, Türkiye. Data were collected using a Sociodemographic Characteristics Form, the Ethical Leadership Scale, the Organizational Communication Climate Scale, and the Organizational Commitment Scale. Data were analyzed using IBM SPSS Statistics version 26. Results: The mean scores were 32.9±8.7 for ethical leadership, 102.8±20.1 for organizational communication climate, and 61.7±10.3 for organizational commitment. Organizational commitment was positively correlated with ethical leadership (r=0.556, p<0.001) and organizational communication climate (r=0.617, p<0.001), and ethical leadership was strongly correlated with communication climate (r= .806, p< .001), supporting all three hypotheses. Both variables jointly explained 38.6% of the variance in organizational commitment (adjusted R² = .386, F (2, 262) = 83.92, p< .001). Communication climate had a stronger standardized coefficient (β = .48, p< .001) than ethical leadership (β = .17, p = .040) and more unique explained variance (ΔR² = .081 vs .010). Nurses with ≥10 years of institutional tenure reported higher communication climate scores than those with 7–9 years (Tukey HSD, p= .003). Conclusion: Ethical leadership and organizational communication climate were significantly associated with nurses’ organizational commitment. When considered simultaneously, organizational communication climate showed a stronger association with organizational commitment than ethical leadership. https://npt.tums.ac.ir/index.php/npt/article/view/5319
