How Many Countries in Asia? All 49 Nations Across 6 Subregions

Asia has 49 internationally recognized sovereign countries, making it the most nation-rich and most populous continent on Earth. Covering 44.58 million km2 -- about 30% of the world's land area -- Asia is home to over 4.7 billion people across six distinct subregions: Central Asia, East Asia, South Asia, Southeast Asia, Western Asia (the Middle East), and North Asia.

The Answer: 49 Countries

Asia has 49 internationally recognized sovereign countries. The United Nations geoscheme divides them into subregions, though some countries (like Russia and Turkey) are transcontinental, straddling the Europe-Asia boundary. The count of 49 includes all nations with territory primarily in Asia.

Countries by Subregion

East Asia (6 Countries)

China, Japan, Mongolia, North Korea, South Korea, Taiwan. East Asia contains the world's second and eleventh largest economies (China and South Korea). China has the second-largest population globally at 1.41 billion. Japan's 125 million people live on an archipelago of 6,852 islands. Mongolia is the most sparsely populated country in the world with just 2 people per km2.

Southeast Asia (11 Countries)

Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Thailand, Timor-Leste, Vietnam. Indonesia is the world's largest archipelago with over 17,000 islands and the fourth most populous country (275 million). Singapore is one of the wealthiest nations per capita despite being just 733 km2. The region is organized through ASEAN (Association of Southeast Asian Nations).

South Asia (8 Countries)

Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, Sri Lanka. India surpassed China in 2023 to become the world's most populous country at 1.44 billion. The region contains the Himalayas, including Mount Everest (8,849 m) on the Nepal-China border. The Maldives is both the smallest Asian country by area (298 km2) and the lowest-lying nation on Earth, with an average elevation of just 1.5 m above sea level.

Central Asia (5 Countries)

Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan. All five are former Soviet republics that gained independence in 1991. Kazakhstan is the largest landlocked country in the world at 2.72 million km2. The region is characterized by vast steppes, desert basins, and mountain ranges. The Silk Road historically passed through all five countries.

Western Asia / Middle East (18 Countries)

• Armenia
• Azerbaijan
• Bahrain
• Cyprus
• Georgia
• Iran
• Iraq
• Israel
• Jordan
• Kuwait
• Lebanon
• Oman
• Palestine
• Qatar
• Saudi Arabia
• Syria
• Turkey
• United Arab Emirates

Western Asia spans from Turkey on the Mediterranean to Oman on the Arabian Sea. Saudi Arabia is the largest country in the subregion (2.15 million km2) and holds the world's second-largest proven oil reserves. The region is the birthplace of three major world religions: Judaism, Christianity, and Islam.

North Asia

Russia's Asian portion (Siberia) comprises about 77% of Russia's total area but holds only about 27% of its population. While Russia is counted as a European country for most purposes, its Asian territory of 13.1 million km2 is larger than any other country in the world.

Key Statistics

Transcontinental Controversies

The exact count of Asian countries depends on how you classify transcontinental nations. Turkey has about 3% of its territory in Europe (Thrace) and 97% in Asia (Anatolia). Russia spans both continents but is generally counted as European. Cyprus is geographically in Asia but politically and culturally aligned with Europe and is an EU member. Egypt has the Sinai Peninsula in Asia but is counted as African. Kazakhstan has a small portion west of the Ural River that falls in Europe. These borderline cases explain why counts of Asian countries range from 44 to 51 depending on the source.
