This study focuses on the Hong Kong Lennon Walls and the communications posted there. We assert that the physical placement of COVID-19 related images on the Lennon Walls of Hong Kong and the replication of symbols and iconography from the Umbrella Movement and the Anti-ELAB Movement situated COVID-19 discourse not only physically within but also symbolically within the contentious politics of Hong Kong. We conclude that the messages and images posted on Lennon Walls between January and April 2020 have used COVID-19 to extend public expression of sentiment on the debates around the Hong Kong government and to further mobilize a sense of Hong Kong identity against China. The findings contribute to the understandings of how the cultural politics surrounding the pandemic became a collective action frame in the mobilization of a localized Hong Kong political identity against the Hong Kong and Chinese governments.
