This study aims to analyze the relationship between authoritarian parenting styles and emotional maturity levels in adolescents, and to assess the extent to which these parenting styles influence the development of emotional maturity. Furthermore, this study seeks to identify factors contributing to the emergence of problems in adolescent emotional maturity. Data collection was conducted at MTS x, with a total of 100 students as respondents. The sampling technique used was saturated sampling (census), so that all members of the population were included in the study sample. The research instruments consisted of an emotional maturity measurement scale and an authoritarian parenting measurement scale. The results showed a positive relationship between authoritarian parenting styles and emotional maturity, with a correlation coefficient of 0.570 and a pvalue <0.01. The Cronbach's Alpha value for this scale was 0.745, indicating that the stronger the authoritarian parenting style, the higher the adolescent's emotional maturity level.
