Mental health is critical to the overall wellbeing of individuals. Therefore the researcher assessed the accessibility and utilization of school-based mental health programs among undergraduates at Babcock University Ilishan-Remo of Ogun State, Nigeria. A cross-sectional survey research design was used for the study. The population consisted of 395 university undergraduates Babcock University. A multi-stage sampling procedure was used. One main instrument was used in collecting data while data collected was analyzed using simple percentage, Pearson Product Moment Correlation and T-test analysis at 0.05 level of significance. The results of the study revealed  that the most three prominent services are: counselling services, social support services, and, interpersonal/social skills training. Additionally, about 3.6% of the total variance in the students’ access of school-based mental health programs is accounted for by socio-demographic factors (F_(1,388) = 2.393; R  =  .189;     R² =  .036; R² Adj. = 0.021, p = .028), gender is the only factor that influenced the access of school-based mental health programs among undergraduates at Babcock University (beta = -.161 and t- = 3.201, p = .000). It was concluded that in order to reverse the poor accessibility and utilization of school-based mental health services, priority should be given to the education of the undergraduates or adolescents on the relevance of utilization of SBMH services. It was recommended that there is a need to focus on equipping the adolescents by providing them with correct and comprehensive school-based mental health services information which can have life-long protective benefits for them.
