Spousal death is one of the most traumatic events that can occur in marital experience and most times, engenders different reactions. The paper investigated the grief reactions of bereaved spouses in Ilorin metropolis, Kwara State. A total of 395 bereaved spouses were selected using a purposive sampling technique. Data were collected from the respondents using an instrument titled "Grief Reaction of Bereaved Spouses Questionnaire" (GRBSQ). The research questions raised were answered with percentages while the hypotheses generated were analysed using t-test statistics and three-way Analysis of Variance (ANOVA) at 0.05 alpha level. The findings of the study indicated that (90.6%) of bereaved spouses in Kwara state have positive grief reactions, while 37 (9.4%) have negative grief reactions. The study further revealed significant differences in the grief reactions of bereaved spouses in Ilorin metropolis based on age at bereavement, nature of death and length of years of loss. Based on these findings, recommendations were made on the desirability of establishing counselling centres in governmental and non-governmental organisations aside from the conventional ones in schools and hospitals. The study also stresses the need for bereaved spouses to be exposed to grief counselling to help them adjust better to their bereavement and educated on the adverse effect of complicated grief as a result of poor adjustment
