This study aims to examine the influence of Person-Job Fit, Person-Organisational Fit, Organisational Culture, and Transformational Leadership Style on Organisational Commitment at the Gunungkidul Regency Trade Office. This study employs a quantitative approach through a survey. Data were collected using an online Google Form questionnaire distributed to 74 respondents via total sampling. Measurements were conducted using a 1-5 Likert scale. Statistical analysis was conducted using multiple regression with SPSS version 26. The findings indicate that individual-job fit, individual-organisational fit, and organisational climate significantly influence organisational commitment, while transformational leadership does not have a significant impact. These results differ from many other studies that often find that transformational leadership can make employees more loyal to the organisation. These findings confirm that individual fit with the job and organisation, as well as a strong organisational culture, play a crucial role in strengthening employee commitment. Therefore, improving alignment between individual characteristics and the work environment can enhance employee loyalty and commitment to the organisation. For the Gunungkidul Regency Trade Office, efforts to create a positive and harmonious work climate are an important strategy for enhancing organisational commitment among its employees.
