The research was conducted to determine whether there is a relationship between adolescents' social media privacy protection skills and social media addiction levels. A total of 499 adolescents between the ages of 15 and 18 participated in this correlational study. The study used a Personal Information Form, the Social Media Privacy Protection Skills Scale for Adolescents, and the Social Media Addiction Scale for Adolescents. Descriptive statistical analysis, point bi-serial and Pearson correlation analysis and regression analysis were used to analyze the data. As a result of the study, it was found that as the adolescents' class level and daily social media usage time increased, their social media addiction increased. It was also found that as adolescents' social media privacy skills increased, their use of social media applications decreased. There is a relationship between adolescents' social media privacy skills and their social media addiction, and as adolescents' social media privacy skills increase, their social media addiction decreases.
