Taking into account the place names of certain tribes and clans, as well as the history of the formation of historical toponyms, is considered one of the relevant topics in studying the issues of a people’s ethnic history. Since toponymic named are connested with several disciplines such as history, geography, literature, and folklore, conducting a comprehensive study will undoubtedly yield valuable results. The relevance of this research is determined by the need to identify the contribution of the Oghus to the ethnic processes of Eurasia and to reconsider historical toponyms from a new perspective. Aim and Objectives. The main aim of the research is to determine the historical and geographical range of Oghuz migrations and to reveal the historical, ethnolinguistic meaning of related geographical names. The objectives include analyzing the origins of toponyms, identifying regional features, and evaluating them in the context of ethnic history. Results. The analysis systematized the Oghuz settlement areas. It was found that many geographical named have preserved the ethnocultural influence of the Oghuz. Historical layers of toponyms shed light on the political and cultural connections of the Oghuz.  Conclusion. The materials discussed provide a deeper understanding of the Oghuz ethnic history. Place names, as part of historical memory, reflect the shared heritage of the Turkic peoples and serve as an important source for future ethnohistorical research.
