Introduction: Spirituality is a multidimensional aspect of human experience. In the context of palliative care, it is an individual resource that can be used to cope with illness and to assign new meanings to suffering. Qualitative studies that aim to investigate the experience of spirituality and the needs of family caregivers in this context are rare. Objective: This meta‐synthesis aimed to synthesise qualitative studies on the experience of spirituality in family caregivers of adult and elderly cancer patients receiving palliative care.
