This paper explores the missions, visions and core values of public and private sector organizations in the Republic of Croatia. The survey was conducted on a total of one hundred and ten organizations, of which fifty-five belong to the public sector and fifty-five to the private sector. During the research, the official websites of the organizations were analyzed and content analysis was used as the research method. Statements of mission, vision and core values are a form of communication between organizations with all stake holders, both employees and the general public. The statements convey a clear message and are part of the identity of the organization and speak about the purpose of the organization, the reason for its existence and its aspirations in the future. Short-form statements actually represent the past, present and future of the organization.Within the organization, statements have the task of connecting and motivating employees and are an integral part of the organizational strategy, and outwardly they have the task of informing, they are part of the image of the organization and generate public opinion about the organization. The purpose of this research is to determine the existence of mission statements, vision and core values on the official websites of organizations, identify key concepts and compare the similarities and differences between published missions, visions and core values of public and private sector organizations in the Republic of Croatia. Survey results have shown that organizations in both sectors recognize the need to communicate through official websites and that the mission, vision and core values statements are often an integral part of that communication. The results of the survey also showed that public sector organizations are more aware of the importance of these statements and publish them more than private sector organizations, and that there is substantial difference in the statements of these two sectors.
