This study investigated the impact of Corporate Social Responsibility (CSR) on customer loyalty, specifically focusing on Nestlé Nigeria Plc. The research addressed the insufficient examination of the direct impact of CSR efforts on customer loyalty within the Nigerian context, despite significant investments by organizations like Nestlé. The study aimed to empirically investigate how environmental responsibility, social and community engagement, and ethical corporate governance practices influence customer loyalty. Utilizing a descriptive research design, the study collected data through questionnaires from a sample of Nigerian consumers. Analysis revealed significant positive correlations between all CSR dimensions (Environmental Responsibility, Social/Community Engagement, and Ethical Responsibility) and customer loyalty (p < 0.01). Ethical Responsibility demonstrated the strongest correlation (r = 0.726), followed by Environmental Responsibility (r = 0.711) and Social/Community Engagement (r = 0.678). A multiple linear regression analysis further confirmed that all three CSR dimensions significantly and positively influence customer loyalty (F (3, 187) = 117.34, p < 0.001). Ethical Responsibility emerged as the strongest predictor (β = 0.345, p < 0.001), with Environmental Responsibility (β = 0.297, p < 0.001) and Social/Community Engagement (β = 0.264, p < 0.001) also showing significant predictive power. All three null hypotheses, stating no significant influence of these CSR dimensions on customer loyalty, were rejected (p < 0.05). The study concludes that effective CSR strategies, particularly those encompassing ethical, environmental, and social dimensions, significantly enhance brand perception and foster sustained customer loyalty. These findings provide actionable insights for businesses in emerging markets, emphasizing the critical role of comprehensive CSR in building and maintaining strong customer relationships.
