In sub-Saharan Africa (SSA), religiosity is a defining feature of social engagement and communal life for older adults. This chapter examines the significant impact that religiosity plays in the roles, experiences, and general well-being of the region’s older adult population. Despite changing social and economic environments, older adults are stewards of cultural and spiritual tradition crucial to maintaining societal cohesiveness in SSA, which is experiencing substantial demographic changes. The chapter explores how religion provides SSA older adults psychological resilience, social capital, and a sense of belonging, and the role of community organizations practices sustaining the well-being of the older adults. It describes how older adults are respected in many SSA cultures as sources of wisdom, spiritual leaders, and intermediaries between the living and the ancestors. The chapter also considers their central role in spiritual leadership across faith traditions spanning Islam, Christianity, and African traditional religion or hybrids of these faiths. Older adults’ spiritual leadership roles are being reshaped by modernity, urbanization, and changes in religious observance. The chapter considers how these modernity trends risk the social isolation and diminished intergenerational support networks for SSA older adults. Finally, the chapter discusses the relationship between religious participation and health, showing how faith-based support systems benefit older individuals’ mental, emotional, and physical health, providing resources including healthcare access, older adults care programs, and support for aging policies. The chapter concludes by highlighting the necessity for further research on the changing role of religion in the aging population of SSA. It calls for policy interventions that integrate traditional religious values with modern approaches to aged care, ensuring that older adults remain active, valued, and supported members of their communities.
