Abstract The Venezuelan Presidential Crisis emerged as a unique polarising political scenario in January 2019, when Juan Guaidó, president of the National Assembly, proclaimed himself interim president of the country, despite the victory obtained by Nicolás Maduro in the May 2018 presidential elections. Considering this context and the role of social media in the spread of polarisation, the present manuscript examines how metaphors and social actor representations act as divisive discursive tools in the tweets of Maduro and Guaidó. To do so, a corpus of tweets posted by these politicians during the first year of the conflict (2019–2020) is analysed, adopting a target-based approach (Stefanowitsch and Gries 2006) to identify the polarising metaphors and a socio-cognitive framework (Darics and Koller 2019; van Leeuwen 2008) to study the social actor representations. The results reveal that these discursive devices help both leaders to construct their social identities, legitimise themselves, delegitimise the other and reproduce their polarising ideological schemas.
