This work is devoted to the results of excavations of the subterranean burial ground and the settlement of Maksimovka I, located in the Samara River basin, and presents the results of excavations at the site in 2022. During this season of fieldwork, two burials dating back to the 14th century AD and one destroyed burial from the Late Chalcolithic were studied. Medieval burials contained bones stretched out on the back, oriented towards the west and southwest, without grave goods. The Eneolithic burial contained the remains of a skeleton positioned semi-sedentaryand oriented to the northeast, without grave goods. A large pit is also attributed to the Copper-Stone Age. Three pits date back to the second half of the 20th century. During this field season, the southeastern part of the Eneolithic structure No. 2 was further explored. The cultural layer of the settlement was poorly saturated with archaeological material. The upper part of the monument has been damaged as a result of modern economic activities. The cultural layer contained ceramics from the Elshan culture, pinned and combed pottery from the Middle Volga Neolithic culture, fragments of Late Chalcolithic vessels with collared edges, finds from the Bronze Age and the 19th – early 20th centuries AD. A compact arrangement of Eneolithic pottery is observed in one section within the studied area. Stone tools were also collected at the site, consisting of a dart tip, scrapers, cores, plates, abrasives and waste from their production. As a result of excavations of the subterranean burial ground and the settlement of Maksimovka I, complexes of different cultures and times were obtained, including materials from the Neolithic, Chalcolithic, Bronze Age, and Middle Ages.
