The study aimed to conduct a comparative analysis of the organisation and operation of jury trials in Ukraine and the United States, as well as to identify problematic aspects and propose recommendations. In addition, the system of jury selection, the organisation of their activities during the trial and the decision-making procedure were addressed. The study was conducted using the methods of legal document analysis, comparative law, and analysis of judicial practice. The results of the study demonstrated significant differences in the organisation of jury trials in Ukraine and the United States. In Ukraine, there are restrictions on the age of jurors, no clear rules for replacing jurors during trials, and no unified system of jury instruction. In contrast to Ukraine, the United States has a clear system of jury selection and replacement, as well as detailed instructions for jurors, which helps to improve their efficiency. As a result of the analysis, several recommendations were made to improve the jury system in Ukraine, in particular: reviewing the age requirements for jury candidates, introducing clear rules for replacing jurors, creating a unified system of jury instruction and enhancing media coverage of jury trials. Implementation of these recommendations will help to improve the effectiveness of jury trials, strengthen public trust in justice and further democratise the judicial process in Ukraine
