The health of children, adolescents, and young adults is a primary global concern. In 2021, there were 2.1 million deaths among children and adolescents. Injuries, violence, communicable diseases, nutritional deficiencies, substance use, non-communicable diseases, and mental health disorders are among the leading causes of death in this age group. Background/objectives: This scoping review aims to identify and describe health promotion and healthy lifestyle programs developed worldwide targeting adolescents and young adults. Methods: A total of 106 programs were included, of which 8 were selected through scientific databases and 98 through other research methods (e.g., government websites and other online sources). Results: The results show that Europe, North America, New Zealand, and the United States of America are the continents and countries with the highest number of programs. Most programs originated before 2020 and are aimed at children, adolescents, and young adults. Mental health, substance and non-substance dependencies, and sexual and reproductive health were the most frequent areas among the available youth programs. Most programs do not mention evaluating or monitoring the services provided. Conclusions: This work allows for a deeper understanding of the programs available for adolescents and young adults, providing an overview of their characteristics. Moreover, it emphasizes the importance of increasing the number of available programs, especially in countries with higher morbidity and mortality rates among the young population. The programs must be based on population studies to better meet their needs. Lastly, programs should become sustainable and integrated into national public policies, accompanied by ongoing training, supervision, and intervision of professionals working in these contexts.
