The aim of this research is to examine the thesis studies on eTwinning in Turkey. In the research, document review, one of the qualitative research methods, was used. The theses, which are the data source in the research, were obtained by using the National Thesis Center database on the website of YÖK (Higher Education Council). The study group of the research consists of 9 thesis studies selected by writing "eTwinning" in the scanning part of the YÖK National Thesis Center page on April 1, 2022. In the examination of thesis studies, theses, the year it was published, the university it was published in, the institute it was published in, the research method, the gender of the researchers, the title of the consultant, and the working group were taken as basis. According to the research findings, there were no thesis studies on eTwinning before 2018, the thesis studies were carried out in 2021 at the most, the theses were published by 9 different universities, the theses were published by the educational sciences institutes the most, the gender of the thesis researchers was the most female, the thesis studies were mostly associate professors. It has been determined that the study group of the theses is mostly English teachers. As a result, it can be said that although the number of teachers and projects interested in eTwinning is high in Turkey, the number of theses related to eTwinning is insufficient. In order to increase the number of academic studies related to eTwinning, it can be suggested that teachers who implement eTwinning projects should be supported and directed in this direction.
