Ordu (Κοτύωρα Cotyora, Armenian: Orti) is a port on the Black Sea coast of Turkey and the capital city of Ordu Province.
, or alternatively the name may be a derivation from the earlier Greek name Kotyora.
Until 1800 Ordu was a small port mainly populated by Pontic Greeks. The population then grew rapidly during the century due mainly to laws passed by the Ottoman Sultan to settle nomadic Turkish tribes in the area. After the Russo-Turkish War (1877–1878), the population grew with the addition of Turks fleeing the Russian controlled Caucasus and Georgia. The ethnic Greeks left the city in 1924 in the Population exchange between Greece and Turkey. Today the population consists of ethnic Turks, Caucasians, a few Muslim Armenians (Hamshenis) and a very small community of the descendants of Greeks who refused to leave.
Ordu has a liberal air compared to the cities further east along this coast and has traditionally been left-leaning and is one of the few municipalities in Turkey controlled by the left-wing DSP (when most of the Black Sea coast voted for the Islamist-leaning AKP).
The local music is typical of the Black Sea region, instruments include the kemençe. The cuisine is typical Turkish dishes such as pide and kebab but includes the well-known 'burnt ice-cream' which comes in two flavours, plain or caramel.
