Civil society is an important part of every state. In addition to enabling citizens to promote their own interests through self-organization, it also enables the performance of many socially useful tasks for society, such as caring for socially excluded groups and other citizens in need. These tasks are performed through various civil society organizations. Civil society organizations have a long history in Croatia. That is why it is expected that a framework for the activities of civil society organizations has been developed in Croatia. This framework consists of the legislative, institutional and financial framework, which are the main part of this paper. The legislative framework consists of laws regulating the establishment and operation of the most important civil society organizations - associations, foundations and institutions. In addition to the basic laws, areas that are important for the operation of civil society organizations, such as collecting and providing humanitarian aid and volunteering, are also legally regulated. The institutional framework rests on three main bodies and institutions for the support of civil society, namely the Office for NGOs of the Government of the Republic of Croatia, the Council for the Development of Civil Society and the National Foundation for the Development of Civil Society. Each of these bodies has a specific task to support the development and operation of civil society organizations. Financial resources are also important for the activities of civil society organizations, for which there are many sources of financing. The main sources of financial resources for civil society organizations in Croatia are income from games of chance, income from EU funds and the state budget. Other sources of financing such as donating to charity and carrying out economic activities, although legally regulated and encouraging, are not a significant source of financial resources for civil society organizations.
