The online environment spreads a strong culture of self-disclosure by providing individuals with countless opportunities for social interaction. This spread has accelerated with the COVID-19 pandemic. As the culture of self-disclosure in the online environment increases, it is curious how families, students, and educators are affected by the situation. It is important for psychological counselors who are engaged in adaptive, preventive, and remedial work in schools to investigate the opportunities and risky aspects of online self-disclosure. It should be carefully examined to see how it will add innovations to counselors' practices. This study aims to present a publication profile on online self-disclosure through bibliometric analysis. In this context, only 256 articles published in English and Turkish related to education, psychology, and family were analyzed. According to the findings, the country with the highest number of publications on online self-disclosure was the USA. The most publishing institutions are universities in the USA. The most productive year on the subject was 2021. It was determined that more and more effective publications were made with adolescents. The most frequently repeated keyword is self-disclosure, while social disruption is the most frequently repeated keyword in terms of psychological factors. It can be said that online self-disclosure is in its infancy in both educational and psychological counseling literature.
