Which mountain range separates the Ganges Plain from the Deccan Plateau in India?

The Vindhya Range separates the Ganges Plain from the Deccan Plateau in India.

The Vindhyas form a discontinuous system of ridges, hills, plateaus, and escarpments across central India. Their northern side borders the Indo-Gangetic Plain, while their southern side leads toward the Deccan Plateau. The range runs broadly east–west, especially across Madhya Pradesh and adjoining regions.

The name can be confusing because “Vindhyas” has had different meanings over time. Older geographical and literary traditions used it broadly for several central Indian hill systems. Modern definitions usually focus on the escarpments and highlands north of the Narmada River. The Satpura Range lies generally south of the Narmada and is a separate, though closely related, mountain system.

The Vindhyas are not especially high by global standards, but they are geographically important. Rivers including the Chambal, Betwa, Ken, and Son drain parts of the range, while the Narmada flows along its southern margin. This makes the Vindhyas a major physical and cultural dividing line within India.
