There is a noticeable absence of scholarship on student-on-student bullying at institutes of higher education in the Caribbean. As a result, this study investigated the phenomenon at a national university in Trinidad and Tobago using a phenomenological case study approach to gather data via semi-structured interviews from five undergraduate and graduate students and a within-case analysis conducted. Thematic analyses revealed nine themes (loneliness, fear, intimidation, low self-esteem, embarrassment, power imbalance, lack of immediate action/indifference, harassment, and quitting). The findings indicated that bullied students feared attending lectures, felt intimidated, disheartened, depressed, anxious, disenchanted, disillusioned, had trouble concentrating on their course of study and had suicidal ideations. These findings inform understandings of student bullying at institutes of higher education and how Caribbean universities can better support students who experience student-on-student bullying on campus. This study has the potential to advance knowledge and improve policy and practice in higher education in the region.
