Background and Objectives: The death of a loved one is one of the most difficult and stressful life events in the world. The effects of death caused by COVID-19 on the mental health of individuals and families are of great importance. This study aims to elucidate the experience of grief in bereaved women following the death of their husbands due to COVID-19 in Qom, Iran. Methods: In this phenomenological study, 12 bereaved women were selected using a purposive sampling method. The information was collected using semi-structured interviews until reaching data saturation. Results: The data analysis led to the extraction of 3 main themes and 10 sub-themes: Complicated grief (ambiguous loss, farewell with no embrace, grieving alone), unconventional grief (strange death, deviation from religious burial customs, virtual mourning), and grief outcome (spiritual experiences, moral panic, social stigma, distrust in healthcare providers). Conclusion: The grief of bereaved women due to the death of their husbands by COVID-19 differs from their mourning for the death caused by other diseases in two aspects. Firstly, according to the majority of women, the cause of death was unclear. This situation intensified their grieving and mourning. Secondly, due to the specific nature of COVID-19 and the necessity of quarantine, they were restricted from having funeral and religious mourning rituals according to the prevalent culture, which resulted in an incomplete mourning process. Gaining spiritual experiences is one positive aspect of grief in women. It is recommended to provide support and care by the healthcare system during pandemics for families, especially bereaved women, to reduce the negative effects of grief.
