This paper mainly explores how real-life social network and social media use are related to loneliness among university students in Bangladesh. To carry out this paper, primary data and several methods are used. This paper uses Lubben Social Network Scale and UCLA loneliness scale to measure the level of real life social network and loneliness, respectively. Besides Pearson's partial correlation matrix is used to find out the correlation between social network, social media use, and loneliness. The study finds that students are averagely engaged in real-life social network and moderately lonely. The study also finds a significantly positive relationship between social media (Facebook) use and loneliness, and a significantly negative relationship between real life social network and loneliness. This paper calls for the students to be careful in using social media and be engaged more in real life social network to avoid loneliness.
