The name derives from the Seljuk Turkish castle of Koçhisar. The prefix Şerefli meaning "honourable" was added by Atatürk in recognition of the men of the town lost at the battle of Gallipoli.

Şereflikoçhisar is believed to have been inhabited since the time of the Hittites and was a thriving town in the Seljuk and Ottoman Empire periods.
