Geography of Türkiye

The Seven Geographical Regions

Established at the First Geography Congress in 1941, Türkiye's seven official geographical regions reflect the country's immense environmental diversity — defined by climate, topography and vegetation, from subtropical coastlines to volcanic highlands above 5,000 m (16,400 ft).

1

Marmara Bölgesi

Marmara Region

The bridge between Europe and Asia. Despite being the second smallest region, it has the highest population density and is the industrial and economic heart of the country. The only region that spans two continents and fully surrounds an internal sea.

Largest city İstanbul
Highest peak Uludağ 2,543 m / 8,343 ft
★ Home to the Bosphorus and Dardanelles — two of the world's most strategic straits.
2

Ege Bölgesi

Aegean Region

Defined by its "perpendicular" mountains, which allow maritime influences to reach deep inland. The landscape is shaped by horst and graben formations — uplifted ridges and fertile river valleys carved by the Gediz, Küçük Menderes and Büyük Menderes rivers.

Largest city İzmir
Highest peak Honaz 2,528 m / 8,294 ft
★ Famous for olives, figs and grapes; major tourism hub and home to the Port of İzmir.
3

Akdeniz Bölgesi

Mediterranean Region

A subtropical region sheltered from cold northern winds by the massive Taurus (Toros) Mountains. The mountains rise abruptly behind the coastline, creating narrow coastal strips — except where the vast, fertile Çukurova Plain opens to the sea.

Largest city Antalya
Highest peak Kızılkaya Central Taurus range
★ The Taurus range and Amanos peaks shelter one of Türkiye's most productive agricultural zones.
4

Karadeniz Bölgesi

Black Sea Region

A long, narrow belt in the north characterised by high humidity, lush forests and the highest rainfall anywhere in Türkiye. The North Anatolian Mountains run parallel to the sea, limiting coastal plains. The region covers approximately one-sixth of the country's total land area.

Largest city Samsun
Highest peak Kaçkar 3,937 m / 12,917 ft
★ Produces nearly all of Türkiye's hazelnuts and tea — a region defined by temperate rainforests.
5

İç Anadolu Bölgesi

Central Anatolia Region

The "Breadbasket of Türkiye" — vast grain fields and open steppe stretching across a high plateau ringed by mountains. Though it appears flat, it contains towering volcanic peaks that rise dramatically above the surrounding plains.

Largest city Ankara (capital)
Highest peak Erciyes 3,917 m / 12,851 ft
★ The driest region in Türkiye, also home to Hasandağ and Karadağ volcanoes, and the cappadocian valleys.
6

Doğu Anadolu Bölgesi

Eastern Anatolia Region

The largest and highest region in Türkiye. Roughly 75% of the land sits at an altitude between 1,500 and 2,000 m (4,900–6,560 ft) — a rugged landscape of volcanic peaks, vast plateaus and deep river valleys from which the Middle East's great rivers are born.

Largest city Erzurum
Highest peak Mount Ağrı (Ararat) 5,137 m / 16,854 ft
★ Contains the headwaters of both the Euphrates (Fırat) and Tigris (Dicle) rivers; also home to inactive volcanoes Süphan and Nemrut.
7

Güneydoğu Anadolu Bölgesi

Southeast Anatolia Region

Known for its wide, uniform plateaus and hot, dry summers. Generally lower and flatter than Eastern Anatolia, though the landscape becomes more uneven toward the east. The region forms Türkiye's portion of the Mesopotamian basin — a cradle of civilisation shaped by the Euphrates and Tigris river systems.

Largest city Gaziantep
Highest peak Karacadağ 1,957 m / 6,421 ft
Key geographic feature Mesopotamia river basins
★ Home to the GAP (Southeastern Anatolia Project) — one of the world's largest integrated irrigation and hydropower schemes, transforming the plains of Urfa and Mardin.
