The issue of minors' right to private life and personal data protection in Lithuania is an important and multifaceted topic, covering the provisions of legal acts, their practical implementation, public awareness and the activities of institutions. Still, there are few scientific studies in Lithuania on minors' right to private life and personal data protection, and scientific research is not often conducted. This scientific article aim is to reveal the legal regulation and practical problematic aspects of ensuring minors' right to private life and personal data protection. After analyzing legal doctrine, court practice and the results of the empirical study, it was revealed that, even with strict legal regulation of minors' private life and personal data protection, it is not enough to protect and ensure these rights. Considering the opinion, experience and knowledge of the research participants, to properly ensure the minor's rights to private life and personal data protection, it is necessary to strengthen legal regulation, take greater preventive measures and promote education, create interinstitutional relations and increase their cooperation and reducing the intervention of state institutions when it is not necessary.
