This study investigated the influence of peer pressure on sexual behavior of undergraduates in Kwara State. Descriptive research design was adopted for the study as well as multi stage sampling procedure. A total of 395 undergraduates participated in the study, four research questions were generated to guide the conduct of the study, while three null hypotheses were formulated and tested at 0.05 level of significance. The instrument used for data collection for this study was a researchers-designed and structured questionnaire entitled “Influence of Peer Pressure Questionnaire” (IPPQ). The findings revealed that the influence of peer pressure on sexual behavior of undergraduates reveals that it leads students to erotic electro-stimulation, prostitution, risk of contracting Sexually Transmitted Diseases (STD) and involvement in incest. There were no significant differences in the influence of peer pressure on sexual behavior of undergraduates in Kwara State based on gender and age.
