Harsh parental discipline is ineffective and potentially harmful to children, yet it is still common, particularly in many African countries. Culturally responsive education programs are needed to shift parenting practices in African countries, but there is limited baseline research to inform such efforts. This study’s objectives were to establish the baseline prevalence of harsh physical discipline practices among primary caregivers of pre-school children in Ethiopia and to identify associated factors to inform intervention efforts. The well-established Parent–Child Conflict Tactics Scale section on physical assault was translated and administered to primary caregivers of 1139 pre-school children aged 4–6 years sampled from four regions of Ethiopia. Trained interviewers also collected basic socio-demographic data. Based on caregiver report, 52.5% (
n
= 598) of the children had experienced harsh physical discipline and an additional 12.7% (
n
= 145) experienced moderate physical discipline in their lifetimes. After controlling for covariates, the factors significantly related to increased likelihood of harsh discipline were geographic region, female caregivers, lack of employment, at least moderate perceived social status, and non-Muslim religion. These data establish a baseline from which to evaluate the impact of future educational interventions designed to shift practices. Information about the correlates can be used to tailor such intervention efforts toward those most likely to use harsh discipline practices.
