Therefore, this study was carried out with the aim of examining the impact of use of social media on students' academic performance in Malaysian Tertiary Institution. In other to measure social media platforms a questionnaire was developed based on past literatures. The independent variables includes: time appropriateness, time duration, Nature of Usage, Health Addiction, Friend-People connection and security/privacy problems while the dependent variable was student academic performance. This research adopted descriptive and explanatory research design. It also employed the use of cross sectional survey method using survey questionnaires that contains 42 items with a Likert Scale (Disagree-1 and 5 for Agree). The sample of 102 students from Erican College was selected using convenient sampling method. The data collected was analyzed using description means and regression via SPSS 21. The Pearson's correlation coefficients of four independent are correlated with student's academic performance while two are not. However, using the regression analysis four variables is significant which include: Time appropriateness, people-friend connection, nature of Usage and health addiction while Time duration and security/privacy problems are not significant. Thus considering the abnormal use of Social media platforms by students, it is expedient that Universities and colleges in Malaysia educate their students to positively use these platforms for educational purposes which will eventually result in a positive impact on their academic performance.
