Beycesultan (pronounced [ˈbejdʒe sulˈtan]) is an archaeological site in western Anatolia (Asia Minor), located about 5 km (3.1 mi) southwest of the modern-day city of Çivril in the Denizli Province of Turkey.

[4] In Early Bronze I there were well-protected Megaron-like structures with porticoes in the front and a fireplace in the main hall.

Western Anatolia (Asia Minor) saw the orientation of sites like Beycesultan more strongly influenced from the west, mainly the Aegean and Crete.

In the Transitional EB/MB (Level VI/V), a stamp seal had Luwian hieroglyphics represented the earliest known evidence of the Indo-European language.

[2] Mallaart assigned the destruction to king Hattusili I (c. 1650-1620 BCE) of the Old Hittite Kingdom fighting the Lands of Arzawa in the west.

After the Anatolian Wars of Suppiluliuma I (c. 1350 BC), the Hittite Empire was the dominant power to the east in this region.

In early 1950s James Mellaart discovered specimens of "champagne-glass" style pottery in a Late Bronze Age context near the site.

[10] Seton Lloyd, along with James Mellaart, excavated Beycesultan on behalf of the British Institute of Archaeology at Ankara for six seasons from 1954 to 1959 with each dig lasting around two months.
