How Big Is North Asia? Area, Countries, and Geographic Features

North Asia covers approximately 13,100,000 square kilometers (5,100,000 square miles), making it the largest subregion of Asia and accounting for roughly one-third of the continent's total land area.

Countries and Territories Included

• Russia (Siberia and the Russian Far East)
• Mongolia
• Northern parts of China (Manchuria, Inner Mongolia, Xinjiang)
• Parts of Kazakhstan and Kyrgyzstan (northern regions)

Key Geographic Characteristics

• Vast steppes and taiga (boreal forests) dominate the landscape.
• The Siberian Arctic extends across the north, with permafrost and tundra.
• Major mountain ranges: Ural Mountains (west), Altai, Sayan, Stanovoy, and Chersky ranges.
• Great rivers: Ob, Yenisey, Lena, and Amur flow northward to the Arctic Ocean.
• Lake Baikal—the world's deepest and oldest freshwater lake.

North Asia's immense size and harsh climate result in very low population density, with most settlements concentrated along the Trans-Siberian Railway and in southern cities like Novosibirsk, Krasnoyarsk, and Irkutsk.
