Objectives: This study is intended to analyze research trends around adolescent suicide in South Korea over the past 20 years (2005–2024) using text-mining techniques. The goal is to identify key themes and changes in the academic discourse related to adolescent suicide to inform future prevention strategies. Methods: A total of 1,378 Korean academic articles were collected from the RISS database using the keywords “adolescent” and “suicide.” After text preprocessing of titles and abstracts, frequency analysis, N-gram (2-gram and 3-gram) analysis, and keyword co-occurrence network analysis were conducted to examine major terms and thematic structures. Results: Word frequency and TF-IDF analyses indicated the high relevance of terms such as “adolescent,” “suicide,” “ideation,” “depression,” “stress,” and “prevention.” The research topics were classified into eight distinct clusters based on network and CONCOR analyses. Conclusions: This study provides a comprehensive overview of trends in South Korean research on adolescent suicide. The findings highlight the need for more preventive and policy-driven research to address the emerging challenges affecting adolescents.
