Ereğli Demir ve Çelik Fabrikaları T.A.Ş. is a Turkish steel producer. The name is a contraction of the Turkish language Ereğli Demir ve Çelik Fabrikaları, which means "Ereğli Iron and Steel Factories". Erdemir occupies the 43rd place among the largest steel companies in the world and is also involved in coal in Turkey.

Coal supplies a quarter of Turkey's primary energy. The heavily subsidised coal industry generates over a third of the country's electricity and emits a third of Turkey's greenhouse gases.
