Many events that occur in the world affect not only the place where they occur but also many regions in the world. This situation necessitates the evaluation of the developments and changes in the world from a universal perspective rather than considering the national interests of each country. The universal evaluation of the problems experienced has led to the emergence of global citizenship. With global citizenship, individuals interact with other people and become sensitive to different events. The individual's interaction with other people and forming public opinion about the events that occur can be realized more quickly and easily with social media, which is preferred by all societies globally. For this reason, the aim of the research was to determine 'the impact of social media on global citizenship' in line with the views of social studies teachers. Phenomenology, a qualitative research method, was preferred in this study. The participants of the study were 22 social study teachers working in secondary schools in the city center. To obtain the data, a semi-structured interview was developed by the researcher after consulting expert opinions. The research concluded that the use of social media has a strong impact on global citizenry, as evidenced by a range of petite responses gathered from the varied related dimensions of importance, awareness, and effect about the subject.
