This article examines the paternal identity of homeless men and the ways in which their relationships with their children are manifested in their life trajectories, thereby extending previous analyses on homeless mothers. Although the literature on homelessness predominantly portrays men, their fatherhood and parental roles remain largely underexplored. Drawing on qualitative life-history interviews with fifty homeless fathers, the study investigates key dimensions including childhood experiences, demographic and educational background, employment history, health status, exposure to and perpetration of violence, and processes of self-identification. The findings are systematically compared with earlier research on homeless mothers to illuminate gendered similarities and divergences in the formation and significance of parental identity. By situating fatherhood within the broader context of homelessness, this study advances a more nuanced understanding of parental roles among homeless populations and offers empirically grounded insights to inform social work practice and the development of targeted support interventions for homeless parents.
