This study aimed to determine the relationship between the foundations of social responsibility for grassroots leaders in local sports organizations, and the foundations of social protection for homeless children, and propose a role for the community organizer in social work to help these leaders to assume their responsibilities in supporting "health, social and economic" protection for homeless children. The researcher conducted his study by using a social responsibility scale applied to (114) members, who represent all directors of the boards at sports clubs and youth centers affiliated to the Department of Youth and Sports in Kafr El-Sheikh (Egypt). Their number was estimated at (5) sports clubs and (10) youth centers. The researcher used the comprehensive inventory method to collect data from the field. The study found that there is a positive relationship, with a statistical significance at a significant level (0.01), between the grassroots leaders' social responsibility and their support of health and socio-economic protection programs for homeless children. It also found that these leaders assume their social responsibilities towards homeless children with an average response "Yes, to an extent". The study reached a proposed vision for the role of the community organizer in social work to develop social responsibility for grassroots leaders at local sports organizations in order to support social protection programs for homeless children.
