Göllüdağ (also Göllü Dağ, Golludag) is a volcanic mountain located in central Turkey.

[1] It was determined that the obsidian found in abundance in Göllü Dağ was used by the prehistoric peoples as early as the Lower Paleolithic period, 800,000 years ago.

[2] Golludag obsidian was mined, processed and traded to distant areas as far as Cyprus, and Syria.

High upon the mountain, a large settlement was found dating back to the 8th century BC, the period of Neo-Hittite civilization.

In 2000, a bone fragment thought to belong to an ancestor of horses was found as the result of the erosion of the mountain slope.
