In this article, we argue that the speeches and policy documents from the later period of Hugo Chávez's presidency exemplify ‘transnational populism’, a form of populist discourse that defies the close association between populism and nationalism that frames the scholarly literatures on both populism and Chávez. We explain why Chávez's populism took this distinctive form by reference to the history of international political thought in Latin America and the political context surrounding the creation of the Alianza Bolivariana para los Pueblos de Nuestra América (Bolivarian Alliance for the Peoples of Our America, ALBA). We suggest that while transnational populism may actually amplify the threat that other scholars have argued populist leaders pose to democratic institutions, it also offers an important corrective to how scholars think about the relationship between populism, democracy and international politics, suggesting that international institutions capable of restraining powerful states are essential to stabilising democracies in the Global South.
