The Pontic–Caspian steppe extends across Eastern Europe to Central Asia, formed by the Caspian and Pontic steppes. It stretches from the northern shores of the Black Sea (the Pontus Euxinus of antiquity) to the northern area around the Caspian Sea, where it ends at the Ural-Caspian narrowing, which joins it with the Kazakh Steppe in Central Asia, making it a part of the larger Eurasian Steppe. Geopolitically, the Pontic–Caspian Steppe extends from northeastern Bulgaria and southeastern Romania through Moldova, southern and eastern Ukraine, through the North Caucasus of southern Russia, and into the Lower Volga region where it straddles the border of southern Russia and western Kazakhstan. Biogeographically, it is a part of the Palearctic realm, and of the temperate grasslands, savannas, and shrublands biome.
The area corresponds to Cimmeria, Scythia, and Sarmatia of classical antiquity. Across several millennia, numerous tribes of nomadic horsemen used the steppe; many of them went on to conquer lands in the settled regions of Central and Eastern Europe, West Asia, and South Asia.
The region contains flora and fauna distinctive of these steppes, covering species that are native to the surrounding waters of the Black Sea, the Caspian Sea, and the Azov Sea. Genetic research has identified this region as the most probable place where horses were first domesticated. The Kurgan hypothesis, the most prevalent theory in Indo-European studies, posits that the steppe was the homeland of the speakers of the Proto-Indo-European language.

The steppe covers an area of 994,000 km2 (384,000 sq mi) of Central and Eastern Europe, that extends from northeastern Bulgaria and southeastern Romania, through Moldova, and southern and eastern Ukraine, through the Northern Caucasus of southern Russia, and into the Lower Volga region of western Kazakhstan, to the east of the Ural Mountains. It is bounded by the East European forest steppe to the north, a transitional zone of mixed grasslands and temperate broadleaf and mixed forests. To the south, the steppe extends to the Black Sea, except the Crimean and western Caucasus mountains' border with the sea, where the Crimean Submediterranean forest complex defines the southern edge of the steppes. It extends to the western shore of the Caspian Sea in the Dagestan region of Russia, but the drier Caspian lowland desert lies between the steppe and Caspian Sea. The Kazakh Steppe bounds the steppe to the east. According to historian Alex M. Feldman, the Pontic-Caspian steppe, together with the forest-steppe and forest lands to the north, forms a historical biogeographical and political region which can be termed Pontic-Caspian Eurasia.
The Ponto-Caspian seas are the remains of the Turgai Sea, an extension of the Paratethys which extended south and east of the Urals and covering much of today's West Siberian Plain in the Mesozoic and Cenozoic.
A significant number of protected areas of the Pontic–Caspian steppe has been under illegal Russian military occupation since the War in Donbas (2014–2022) and the 2022 Russian invasion of Ukraine. There has been much negative environmental impact of the war in eastern Ukraine, and later environmental impact of the Russian invasion of Ukraine. For instance, the Dzharylhach National Nature Park was reportedly thoroughly devastated by uncontrolled fires in November 2023 due to "Russian armed aggression" during the Russian occupation of Kherson Oblast.
