The present study investigates the mediating effect of organizational commitment between emotional intelligence (EI) and mental health (MH). The participants of the study were 252 nurses working in six big districts of KPK (Peshawar, Mardan, Swat, Sawabi, Charsadda & Nowshehra), Pakistan. Data were collected through Organizational Commitment Scale (Meyer, Allen, & Smith, 1993), The Hospital Anxiety and Depression Scale (Zigmond & Snaith, 1983) and EI Scale (Wong & Law, 2002). Both EI and organizational commitment were significantly related to MH. The results of Structure Equation Modeling (SEM) explored that organizational commitment partially mediated the relationship between EI and MH. The final three factor model explored a significant path from EI to MH via organizational commitment. The findings discuss the effect of EI on MH.
