This study intends to examine corporate social responsibility (CSR) in Pakistan's banking sector, CSR disclosure practices and their impact on financial performance. For the study, relevant data was collected from the banks' annual reports, financial websites, the State Bank of Pakistan (SBP) and the Pakistan Stock Exchange (PSE) from 2008 to 2018. The methods utilized in this research study were content analysis and panel data techniques. The results indicate an increase in overall CSR disclosure by all banks in the sample and the findings suggest the involvement of commercial banks in CSR activities, and its proper disclosure has helped to improve their accounting-based financial performance proxied by the return on equity (ROE) and return on assets (ROA). The research findings contribute to a better understanding of the CSR practices in the financial sector of an emerging country, which makes a dynamic effort to develop its financial culture and can encourage rapprochement with Pakistan's financial sector.
