["Global Networks, EarlyView. ", "\nAbstract\nDiasporas play a critical role in home‐country politics by supporting social, political, and economic change therein. Yet, regimes countermobilize against activists abroad by repressing their diasporas. This paper investigates a widespread but overlooked method in the transnational repression toolkit: that of ‘proxy punishment’, that is, the abuse of family members at home as a means to manipulate and subjugate dissidents abroad. Using 246 original interviews with diaspora activists from Syria, Iran, Egypt, and Libya, the analysis demonstrates that regimes deployed five tactics against diaspora members’ non‐activist families at home: harm and confinement, threats and harassment, forced participation in regime propaganda and slander, resource deprivation, and travel bans. We then identify the mechanisms shaping how diaspora members responded to this repertoire. The paper concludes with implications for research on transnational diaspora activism, globalized authoritarianism, and collective dimensions of the repression‐dissent nexus.\n"]
