The purpose of the article: analysis of the ways and forms of creating museum funds in domestic museums at the beginning of the 20th century, using the example of the "Kyiv Art Gallery" National Museum. The methodology of research: the research methodology involves the application of general scientific methods, such as synthesis, analysis, classification, and periodization of scientific data, as well as special research methods, including historical and comparative-historical approaches. The scientific novelty: the research expands our understanding of the "Kyiv Art Gallery" National Museum's activities, specifically the processes of forming its museum fund in the 1920s. Additionally, archival data on the museum's functioning have been supplemented and expanded. Conclusions. Based on the analysis of the formation of museum funds in domestic museums in the 1920s, using the example of the "Kyiv Art Gallery" National Museum, it becomes clear that the museum's fund was formed through the expropriation and nationalization of private art collections, particularly the Tereshchenko family and O. Hansen's collections, and their subsequent redistribution among museums, thus determining the museum's development concept.
