Defining the Vast Boundaries of Siberia

Where Does Siberia Begin and End?

Siberia's geographical borders are not universally fixed; they shift depending on whether you're using physical geography, political boundaries, or historical regions. However, a widely accepted framework outlines its immense span across northern Asia.

Western Border: The Ural Mountains

The Ural Mountains serve as the classic dividing line between Europe and Asia. Siberia's western edge traces the Urals from the Arctic coast southward to the mountains' southern terminus near the Caspian Sea.

Northern Border: The Arctic Ocean

The northern frontier aligns with the Arctic Ocean coastline, including the Russian islands of Severnaya Zemlya, the Franz Josef Archipelago, and the New Siberian Islands.

Southern Border: A Zone of Transition

The southern boundary is the most debated. Common delineations include:

• The great Central Asian mountain barriers: the Altai, Pamir, and Tien Shan ranges.
• The southern administrative limits of Russian republics like Bashkortostan, Tatarstan, and the Altai Republic.
• The cultural-historical frontier separating Siberia from the Volga region, the Caucasus, and the Kazakh Steppe.

Eastern Border: The Pacific Watershed

The eastern limit follows the continental divide between rivers draining into the Arctic Ocean and those flowing into the Pacific. It encompasses the Pacific coastline, the Kamchatka Peninsula, Sakhalin Island, and the Kuril Islands.
