Almost two-thirds of students in Northern Ireland who took part in a joint study reported an unwanted sexual experience.
That is according to research by academics from Ulster University (UU) and Queen's University Belfast (QUB).
More than 1,000 students from QUB and UU were surveyed for the UNSEENATUNI study.
Justice Minister Naomi Long said the findings were "alarming" and made for "uncomfortable reading".
The authors acknowledged those surveyed only represent about 2% of the entire student population at the universities.
