Objectives: Research on the needs of family caregivers of people living with cancer remains disproportionately focused in high income contexts. This research gap adds to the critical challenge on global equitable delivery of cancer care. This study describes the roles of family caregivers of people living with cancer in Vietnam and possible implications for intervention development. Methods: Semi‐structured interviews and focus groups with family caregivers (n = 20) and health care providers (n = 22) were conducted in two national oncology hospitals.
