Corporate social responsibility can be one of the basic considerations for investors to invest their capital, and can improve the company's image to attract consumer attention so that the company achieves its goals to the maximum. The trust of consumers and investors will have a positive impact on the company's Financial Performance. The purpose of this study was to determine the effect of corporate social responsibility on financial performance as measured by Return On Assets, Return On Equity, Return On Sales, Net Profit Margin, and Earning Per Share. The data analysis method used is panel data regression analysis using Eviews 12. The results showed that partially corporate social responsibility has a significant positive effect on Return On Assets, Return On Equity, Return On Sales, and Net Profit Margin. Corporate Social Responsibility has no effect on Earning Per Share. This proves the importance for investors when investing in a company to see aspects of the company's responsibility to internal and external parties through the disclosure of Corporate Social Responsibility in the annual report or sustainability report. Keywords — Corporate Social Responsibility, Return On Assets, Return On Equity, Return On Sales, Net Profit Margin, Earning Per Share.
