This chapter develops the 'transnationalisation of intimacy' as a conceptual lens to critically investigate the performance, embodiment and negotiation of transnational familial intimacy in a fast-evolving globalising and digital society. This is achieved by conducting a state-ofthe-art review of theories and empirical studies on family relations and practices in a transnational context. We discuss how transnational familial intimacy is shaped by the conflation of structural and technological forces, which at once reinforces and challenges social and cultural norms of the family. We first show that intimate family practices are engendered and undermined by mobility regimes and infrastructures. We then illuminate how communicative practices pave the way for transnational linkages. However, inequalities may play out in the transnationalisation of familial intimacy, especially when material and symbolic forces are embedded in an unequal terrain. Finally, we consider the implications of transnationalism for (de)normalising family relations and practices, in creating distinctive, new transnational forms of intimacy between family members. In sum, this chapter draws attention to the mutually constitutive nature of transnationalism and changing family relations in a global and digital age.
