Loneliness is a psychosocial problem that affects individuals' and communities' mental health and well-being. Young adults from developing countries risk developing high levels of loneliness. The current review discusses the characteristics of studies on loneliness among young adults in India. The inclusion criteria of the review included peer-reviewed journal articles published in English, presenting any quantitative evidence on loneliness among young adults in India. Eight articles were identified and categorized under three major themes: loneliness and personality, loneliness and internet usage, loneliness and well-being. Loneliness is not recognized or assessed as a mental health problem in India. This review provides a ground to recognize loneliness as a mental health problem in India. However, most of the studies have small samples and use scales that have been standardized in western settings. Future research with a large sample will provide substantial evidence of loneliness in India.
