In this article we introduce the concept of soft nationalism through a case-study analysis of short videos by US-born rapper MC Jin (Jin Au-Yeung), who is of Chinese background. Jin's creative output, we argue, with its cross-cultural and grassroots invocations of Chinese identity, ethnicity, tradition, language and belonging, complicates existing theories of nationalism. To address these complications we develop the term ‘soft nationalism’, to describe forms of nationalism that are neither ‘hard’, ‘hot’ and bellicose nor ‘banal’ or ‘everyday’. Like soft power, soft nationalism carries intent but speaks quietly, and is practised everywhere but often found in China, in the context of a recent surge of participatory online nationalism.
