Abstract: The study investigated family violence and sibling abuse in Nigerian families. This is based on the observation that there is an increasing instance of violence in Nigerian families. Relevant literatures were reviewed for the study. Two research hypotheses were developed for the study. The population used for the study were all families in Abraka in Delta state. Samples of 380 respondents were randomly selected for the study which comprised of staff and students of Delta state university community in Abraka and students of primary and secondary schools in Abraka community. The instrument for data collection was a questionnaire titled Family Violence and Siblings Abuse. The 44 item instrument has a coefficient of r = 0.75 to analyse the data collected for the study, the t-test and multiple regression statistics was used. The analysis of data revealed that family types do not affect experiences of sibling abuse. This is because children from monogamous and polygamous homes do not differ in their experiences of sibling abuse. Analysis of data also revealed that siblings’ abuse is real to Nigerian families. This is a phenomenon which has eaten deep into the family system in the country. It was therefore suggested that there should be some of awareness campaign that will help to change this menace in Nigerian families. The study therefore, recommends that structures should be put on ground to check this ugly phenomenon that is gradually destroying the personalities of young children. This can be done through effective counselling for family members, rehabilitation for abusive parents and penalty to be imposed on anyone who indulges in this behaviour.
