Adolescence is a time when peers play an increasingly important role in the lives of youth. The study examined the impact of peer influence on behavior of adolescent students towards academic success in secondary schools in Ilorin South L.G.A in Kwara State. The Study obtained its figures and data from secondary sources. This study discussed adolescent as a concept, the positive and negative influence of peer groups on adolescent in relation to their studies and peer selection and influence processes in classroom. The finding shows that peer groups have positive and negative influence on the academic performance of students at schools. However, parents who are not well behaved can influence their wards/children. In addition teachers who are not responsible and not discipline can influence their students to becoming like them. Furthermore, school managers who are reckless indecision making and taking can influence students' behavior and performance at schools. The study recommends among others that trained counselors should be posted to all the secondary schools so as to help counsel the adolescents with negative influences and also parents should have effective supervision by not allowing other home environmental actors to distract their children.
