Abstract Grassroots movements such as Poder Quince exemplify how Latinx youth intertwine their cultural heritage and traditions with civic action to create positive change within their communities. Parents' cultural socialization messages have been shown to instill cultural pride and encourage prosocial behaviors (e.g., helping others, caring for younger siblings). However, there is a dearth of research on the sociopolitical discussions Latinx adolescents have with their parents and the mechanisms by which cultural socialization encourages prosocial civic development. Drawing on data from a sample of 269 self‐identified Latinx youth from three Midwestern US schools, the present study explored the direct links between parental cultural socialization and adolescents' sense of social responsibility (i.e., concern for others and caring for community) as well as the potential indirect associations via sociopolitical and civic socialization at home. Our findings suggest direct associations between cultural socialization and caring for their communities. Additionally, we observed indirect associations between cultural socialization and youths' social responsibility via family civic socialization practices and engagement in sociopolitical discussions taking place in the home.
