Turkey lies on two continents: roughly 97% of its land sits in Asia, on the Anatolian Peninsula, while about 3% sits in Europe, in a region called Eastern Thrace. This split makes Turkey a transcontinental country, and the city of Istanbul famously straddles the boundary between Europe and Asia.
Two Continents, One Country
The vast majority of Turkey occupies a peninsula known as Anatolia, or Asia Minor, which belongs to Western Asia. This Asian portion stretches from the Aegean coast in the west to the borders of Georgia, Armenia, Iran, Iraq, and Syria in the east and south. Anatolia accounts for the bulk of Turkey's total area of roughly 783,562 km².
The European slice of Turkey is called Eastern Thrace. Though it makes up only about 3% of the national territory, it borders Greece and Bulgaria and contains the European districts of Istanbul. So while Turkey is overwhelmingly Asian by land area, it has a genuine and historically important foothold in Europe.
The Boundary Between Europe and Asia
The dividing line between the two continents runs through the heart of Turkey via three connected waterways. From north to south these are the Bosphorus Strait, the Sea of Marmara, and the Dardanelles. Together they form a natural water boundary separating European Thrace from Asian Anatolia.
The Bosphorus is the most famous of these. Cutting directly through Istanbul, it narrows to roughly 700 meters at its tightest point, making it one of the narrowest straits in the world to separate two continents. Several bridges and an undersea rail link now connect the two sides, allowing residents to cross from one continent to the other in minutes.
Where the Major Cities Sit
Turkey's capital, Ankara, lies firmly in the Asian interior on the Central Anatolian plateau. Istanbul, the country's largest city and economic hub, is unusual in that it spans both continents at once, with neighborhoods on the European side and the Asian side linked by ferries, bridges, and tunnels.
- Ankara (capital): Asia, central Anatolia
- Istanbul (largest city): transcontinental, split by the Bosphorus
- Izmir, Antalya, Bursa: Asia, along or near the western and southern coasts
- Edirne: Europe, in Eastern Thrace near the Greek and Bulgarian borders
Istanbul is often described as the only major city in the world built across two continents, a fact that captures Turkey's bridging role between East and West.
Landscape Across the Divide
Turkey's geography is remarkably varied for a single country. The Pontic Mountains run along the Black Sea coast in the north, the Taurus Mountains rise in the south near the Mediterranean, and a dry, elevated plateau dominates the center. The highest point, Mount Ararat, reaches about 5,137 meters and stands in the far east, in the Asian part of the country.
The nation's long coastline, stretching some 7,200 kilometers, touches the Black Sea, the Sea of Marmara, the Aegean, and the Mediterranean. This combination of mountains, plateaus, and seas has shaped settlement, agriculture, and trade across both the Asian and European portions for millennia.

Why the Question Causes Confusion
People often debate whether Turkey is "European" or "Asian," and the confusion is understandable. Geographically, the answer is clear: Turkey is predominantly in Asia, with a smaller part in Europe. The mix-up usually comes from politics and culture rather than geography.
Turkey is a member of NATO and the Council of Europe, has long pursued European Union membership, and competes in European sporting and cultural events. Centuries earlier, the Ottoman Empire ruled large stretches of southeastern Europe. These ties give Turkey a strong European dimension even though most of its land is on the Asian side of the Bosphorus.
Frequently Asked Questions
Is Turkey in Europe or Asia?
Both. About 97% of Turkey is in Asia on the Anatolian Peninsula, and about 3% is in Europe in the region of Eastern Thrace. This makes it a transcontinental country.
What separates the European and Asian parts of Turkey?
The Bosphorus Strait, the Sea of Marmara, and the Dardanelles form the water boundary between European Thrace and Asian Anatolia. The Bosphorus runs right through Istanbul.
Is Istanbul in Europe or Asia?
Istanbul is in both. The city is split by the Bosphorus, so part of it lies in Europe and part in Asia, making it the most famous transcontinental city in the world.
Is the capital of Turkey in Europe or Asia?
Ankara, Turkey's capital, is in Asia. It sits on the Central Anatolian plateau well to the east of the Bosphorus and the European part of the country.
