Corporate Social Responsibility (CSR) has evolved into a strategic imperative for organizations seeking sustainable growth and stakeholder trust. This study examines the impact of CSR practices on organizational performance, with specific reference to United Bank for Africa (UBA) in Ibadan, Nigeria. Using a quantitative research design, data were collected from 100 respondents comprising customers, staff, and management through a structured questionnaire. The study evaluates the relationship between CSR activities-economic, legal, and ethical responsibilities and key performance indicators such as profitability, reputation, and customer loyalty. Findings indicate that CSR significantly contributes to organizational success by enhancing public image, strengthening stakeholder relationships, and fostering long-term profitability. However, tensions between short-term profit maximization and long-term social responsibility persist. The study concludes that integrating CSR into core business strategy is essential for sustainable competitive advantage.
