Zoos are the most visited attractions, annually recording millions of visits around the world. For many people in urban areas they represent a window into the world of nature. The concept of corporate social responsibility is based on two aspects on companies. One sees companies as for-profit institutions that offer goods and services to the general public, and the other view companies as important centres of power and decision-making, whose actions have a tangible impact on the lives of individuals and society. The society demands the responsible use of that power from companies, on the benefit of society itself. Although not originally conceived as a CSR model, stakeholder theory is the most common approach to analysing and implementing corporate social responsibility, starting with identifying and analysing stakeholders to whom the company has an obligation and without whom it could not operate. Awareness of the importance of corporate social responsibility in Croatia exists, but implementation is mostly lagging for economic reasons. A study of the practice of socially responsible business of the Zagreb Zoo was conducted. The aim of the research was to determine if the Zoo Zagreb is a positive example of socially responsible business in Croatia that could be example to other similar organizations. The conducted research shows the awareness of the concept of socially responsible business among the employees of the Zagreb Zoo and its integration into the activities of the Zagreb Zoo.
