Past research has explored social media grief; however, the motivations for using a range of social media sites, specifically by young millennials, to grieve death fail to be explored expansively in existing thanatology research. Fourteen young millennials participated in individual semi-structured interviews, specifically questioning their motivations for using social media sites to grieve. The interviews were analysed using the thematic analysis framework identified by Braun and Clarke (2013). Four themes were generated: online influence, to announce the death, personal benefit and the hypocrisy of online mourning. The online influence theme suggests that individuals are motivated to grieve due to online influence and pressure. The personal benefit theme suggested social media present many benefits for the bereaved, including continuing bonds, which motivated them to use these platforms. The analysis also indicated that within the motivations there was hypocrisy regarding how young millennials perceive their grief posting activity when compared to others.
