Performance is the process of providing lasting success to organizations by improving the skills of employees. The dimension of organizational culture as an important factor in organizational performance has been rarely studied, especially in public sector banks in Pakistan. The main purpose of this study is to expand the related literature, as well as to examine the relationship between the dimension of organizational culture (i.e., involvement culture, consistency culture, adaptability culture, and mission culture and organizational performance. The questionnaires in this study were collected from employees of 320 banks who are actually working in public sector banks in Pakistan. The samples included both male and female bank employees. The results show that the dimensions of organizational culture such as; involvement culture, consistency culture, adaptability culture, and mission culture were significantly and positively related to organizational performance in Pakistan's public banking sector. The data was examined by using Smart PLS 3.2.9. This study differs from other studies in that it examines the influence of the dimension of organizational culture on non-financial indicators of organizational performance in Pakistan's banking sector, especially in public sector banks.
