Abstract. The purpose and the task of the article is to analyze the application of the systems method in legal research and to reveal the role of the systematic approach in the methodology of modern jurisprudence. Methods. The main research method is a system-structural approach, which involves solving the problem of using the system method of scientific knowledge in legal research. Also research methods are: logical method, scientific abstraction, comparative analysis and synthesis, systematization and grouping. Research results. The main purpose of the systematic approach is realized only in the definition of one object that is studied from different angles. At the same time, the systematic method of cognition requires a more comprehensive approach to the study of the entire methodology of modern jurisprudence. This, in turn, will be able to reveal the essence of this type of methodology in relation to individual objects of study in jurisprudence. In the methodology of modern jurisprudence, the systematic method of research is a very effective cognitive tool, as it allows to combine into a single scientific picture of knowledge that has obtained from different branches of science and through the using of various methodological approaches. The systematic method helps to investigate a specific object of knowledge comprehensively, taking into account the direct reference to the object. At the same time there is a multiplication of knowledge from other branch sciences. In this way the scientific potential of the systematic method of research shows in modern jurisprudence. Using this general scientific method of cognition, it is possible to identify general properties of legal phenomena that cannot be detected by studying legal phenomena through the prism of formal-logical analysis. Key words: methodology, methodology of jurisprudence, law, theory of the state and law, jurisprudence, cognition, scientific research, legal science, methods of scientific cognition, methods of modern jurisprudence, system, systematic method, systematic approach.
