    The widespread use of digital technologies and the increasing prevalence of internet usage in a globalized world have significantly influenced individuals' personality traits. In particular, the restriction of face-to-face interactions during global pandemics has led individuals to maintain their lives in digital environments. These developments have made it increasingly important to investigate the relationship between internet use and personality characteristics. This study aims to adapt the Online Narcissistic Personality Inventory (ONPI), developed by Chou and Farn (2015) based on the 40-item Narcissistic Personality Inventory by Raskin and Terry (1988), into Turkish and to examine its psychometric properties. The study sample consists of 397 individuals from diverse age groups and socio-demographic backgrounds. Data was analyzed using SPSS 30 and AMOS 30 software. According to the results of the exploratory factor analysis, the item factor loadings ranged from 0.466 to 0.812, and the total variance explained by the scale was found to be 58.36%. Confirmatory factor analysis results (Chi-square/df:2.584; RMSEA:0.063; NFI: 0.84; IFI: 0.90; TLI: 0.87; CFI: 0.90; GFI: 0.90) indicated that the scale exhibits a five-factor structure with 27 items. The internal consistency of the scale was high, with a Cronbach's alpha coefficient of 0.93. Additionally, the item total correlations ranged between 0.326 and 0.700. The findings demonstrate that the Turkish adaptation of the Online Narcissistic Personality Inventory is a valid and reliable measurement tool.
