The article is devoted to the analysis of the system of speech genres of modern Ukrainian presidential discourse. The study of presidential discourse as one of the varie-ties of political discourse is carried out in a communicative and pragmatic aspect. This involved taking into account the features of communicative interaction of political in-teraction participants, selected communication strategies and tactics, and identifying communicative intentions. One of the new genres of Ukrainian presidential discourse is considered – a petition to the President of Ukraine. Petitions of citizens to the President for 2015-2023 were analyzed and the structural-semantic and communicative-pragmatic features of this genre were determined. The remote and mediated nature of petitions as a genre of electronic communication between the head of state and citizens of Ukraine is taken into account. The main communicative strategies of speakers in petitions and the specifi cs of the President’s communicative behavior as addressee and respondent are characterized. Attention is focused on linguistic means of achieving the perlocutionary eff ect in the speech genre of the petition. The communicative intention of encouragement is defi ned as the main one in the petition, which determines the implementation of speech acts of off er and request. The two-component structure of the petition was considered and the speaker’s own appeal and the addressee’s response in communicative interaction with the participation of an indirect mass addressee were analyzed. The structural elements of the President’s response as a component of the speech genre of the petition are considered and its performative nature is determined. The problems of achieving perlocutionary eff ect in petitions and low eff ectiveness in political discourse are characterized.
