The study investigated the causes, consequences and control of students' crises in public and private universities in Nigeria. The study population comprised all the 104 approved universities in the country from which a sample of 8 universities (5 public and 3 private) was taken. 250 members of staff and 350 students were chosen in public universities and 150 members of staff and 210 students were chosen in private universities. The method of selection was by stratified random sampling. The instrument used was a questionnaire while the data collected were analyzed using chi-square. The findings show that the level of students' crises in public and private universities was high. Some of the causes of the crises were cultism and the failure of university authorities to meet students' demands. The consequences of students' crises were found to include loss of lives and properties and disruption of university programmes. Based on the findings, it was recommended that university authorities should imbibe the use of the dialogue strategy in controlling students' crises.
