Modern scientific research of the problems of constitutional jurisdiction in Ukraine is conditioned not only by their established theoretical and practical significance for legal doctrine and law enforcement. In the context of modern global challenges and threats that inevitably affect the domestic legal order of Ukraine, taking into consideration the national problems in the field of human rights and freedoms, interaction between state and society, lawmaking, law enforcement and administration of justice, etc., the need to strengthen the institutional capacity of the Constitutional Court is an important scientific and practical task. It is aimed at strengthening the stability of the institution of constitutional jurisdiction in difficult sociopolitical situations, restoring public confidence in the Constitutional Court and the state in general, improving the legal protection of the Constitution of Ukraine and ensuring its supremacy, reviving respect for the Basic Law and the rule of law, accommodating the functioning of the Constitutional Court to the best international standards of constitutional jurisdiction. The purpose of the article is to substantiate the study of the problem of strengthening the institutional capacity of the Constitutional Court of Ukraine as a complex scientific and applied issue, which provides for its solution in the interdisciplinary scientific space. General scientific research methods, sociological method, structural-functional, as well as interdisciplinary approaches, are used. The institutional capacity of the Constitutional Court of Ukraine is considered as an institutional property of a body of constitutional jurisdiction, which reflects its organisational and functional ability to ensure the implementation of its tasks, functions, and powers under certain conditions and resources. Indicators of the institutional capacity of the Constitutional Court are efficiency, stability, and adaptability to changes. Strengthening the institutional capacity of the Constitutional Court should take place through legal support for strengthening its independence from political influence, improving mechanisms for selecting candidates for judges, modernising constitutional proceedings, developing a mechanism for the Court's interaction with the public, and so on. The main directions of the study of the institutional capacity of the Constitutional Court are determined
