Corporate Social Responsibility, hereinafter referred to as CSR, is becoming an imperative of every modern organization that strives for growth and development. The importance of CSR is not limited to the organization, but also to its environment and community, and today it is one of the fundamental principles of every organization. Corporate social responsibility benefits companies, as well as their stakeholders. With the implementation of CSR in business, the main concern is focused on employees, clients, partners, society, and the environment. Topic of this paper "Analysis of key elements of corporate social responsibility of selected insurance companies" is based on the assumptions of insufficient implementation by company management in Croatia and insufficient public awareness of the modern concept of social responsibility. The aim of this paper is to understand the benefits that this way of doing business brings to the company and to precisely define socially responsible business and its division, define insurance companies and their business, and compare the application of CSR practice in four selected insurance companies. Great attention has been paid to the care of companies for their employees, society and the environment. Based on the interview with the employees of Croatia osiguranje d.d., Grawe Hrvatska d.d., UNIQA osiguranje d.d. and Wiener osiguranje d.d. it was noticed that all companies have successfully implemented CSR in their business, but each company does it in its own way with minor differences.
