Job satisfaction has been one of the most influential and sensitive factors in understanding employee motivation, their sense of competence, and job performance. Employees' feelings of pleasure, happiness, and satisfaction with their jobs lead to professionalism, attachment, and the enhancement of organizational culture. It also fosters increased organizational commitment and loyalty, reduces absenteeism and job turnover, ensures adherence to organizational and job-related regulations, and decreases sabotage and organizational vandalism. Over recent decades in Iran, job satisfaction has played a crucial role in organizational development, transformation, and dynamism, contributing to its growth and prosperity. Accordingly, the main objective of this research is to examine the impact of job satisfaction and its components on organizational commitment using secondary analysis and empirical data analysis. The research method employs quantitative meta-analysis and systematic review, relying on published scientific sources and documents from Noormags, MagIran, and IranDoc between 2003 and 2023. From a statistical population of 98 studies, 50 documents were selected through non-probability sampling (purposive and convenience sampling) after screening and applying inclusion criteria, and were entered into CMA2 software. The tests used include Cohen’s *d*, Fisher’s *f*, and Q-tests. Ultimately, the effect size coefficients (Cohen and Fisher) indicate that job satisfaction has a significant overall impact on organizational commitment, explaining and predicting 55% of it.
