One of the major phenomena threatening organizations is the mental and emotional shocks that are created in organizations and lead to devastating consequences. The main objective of this study is to investigate the role of organizational mindfulness on organizational trauma with a focus on mediating role of political intelligence among managers. This study is an applied research in terms of its objectives, and a descriptive-survey study in terms of data collection. The research population consisted of 240 employees working in central department of the Social Security Organization of Fars province, of whom 147 employees were selected through simple random sampling using the Cochran formula. The data were collected using organizational mindfulness questionnaire (Pahlavan-sadegh&Abdollahi, 2016), organizational trauma scale (Vivian&Horman, 2015), and political intelligence inventory (Freis et al., 2005). Validity of the questionnaire was confirmed through content validity method and its reliability was checked and confirmed through Cronbach's alpha. Structural equation modeling method in AMOS 23 was used for data analysis. The results of the study showed that organizational mindfulness and political intelligence have a negative and significant effect on organizational trauma. It was also found that organizational mindfulness can have a significant effect on reducing organizational trauma through managers’ political intelligence.
