Background: Many adolescents had engaged in unhealthy sexual behavior that can result in unintended health outcomes. In theory, the adolescent sexual behavior is influenced by a complex set of interactions between biology, genetics, individual perception, personality characteristics, and sociocultural norms and values. This study aimed to determine the influence of internal and external factors on preventive reproductive health behavior in adolescents, in Banjarmasin, Kalimantan, using Health Belief Model. Subjects and Method: This was an analytic observational study with the cross-sectional design. The study was conducted at 10 senior high schools in Banjarmasin, Kalimantan. A total sample of 200 grade XI students was selected for this study by proportional stratified random sampling. The dependent variable was preventive reproductive health behavior. The independent variables were perceived susceptibility, perceived seriousness, perceived threat, perceived benefit, perceived barrier, self-efficacy, the role of parents, peer role, and information access. The data were collected by questionnaire and analyzed by path analysis. Results: The strong role of parents (b=0.05; SE= 0.01; p<0.001), perceived benefit (b=0.06; SE= 0.02; p=0.006), perceived threat (b=0.10; SE= 0.02; p<0.001), self-efficacy (b=0.13; SE= 0.01; p<0.001), and peer role (b=0.06; SE= 0.01; p<0.001) positively affected preventive reproductive health behavior. Perceived barrier (b= -0.03; SE= 0.01; p=0.026) negatively affected preventive reproductive health behavior. Perceived threat increased with increasing role of parents (b=0.05; SE= 0.02; p= 0.059), perceived susceptibility (b=0.21; SE= 0.05; p
