Background: Malnutrition among preschool children is still a serious public health problem in Nigeria and other developing countries. The critical role fathers play in providing support in improving infant, young child and maternal nutrition cannot be overemphasized. Therefore, the current study seeks to explore the level of male involvement in infant and young child nutrition and its association with nutritional status. Methodology: A cross sectional study among 190 households, 5 focus group discussions, and 5 key informant interviews were conducted in Birnin Kebbi metropolis of Kebbi State in Nigeria. Anthropometric measurement, biochemical and physical evaluation were used to assess nutritional status of preschool children of the respondents. Focus group discussions and in-depth interviews conducted and summarized into themes. Results: The study revealed that higher percentage of the males provided money to buy food for the children (93.6%), and only 9.8% have ever accompanied mothers to young child clinics. Conclusion: In this study, most males were involved in buying food for their children, and providing money for transport to young child clinics was associated with normal nutritional status of children less than 5 years in the study area.
