Kul Tepe Jolfa (Gargar Tepesi) (Kul Tapeh) is an ancient archaeological site in the Jolfa County of Iran, located in the city of Hadishahr, about 10 km south from the Araxes River.

[3] Later, the Middle and Late Bronze Age (Urmia ware), and Iron and Urartian/Achaemenid periods are also attested.

This is a small and very old site that begins in the Late Neolithic/Transitional Chalcolithic period, similar to Hajji Firuz Tepe; it may have started c. 6000 BC.

According to Akbar Abedi, "To sum up, the emerging picture suggests that the Chaff-Faced Ware system, whose focus was the highlands, was progressively challenged during the 4th millennium in the north as in the south, by the Kura––Araxes and Uruk expansions, respectively.

After a period of coexistence with both, the Chaff-Faced Ware culture was superseded in the highlands by the Kura-Araxes phenomenon, whose driving forces probably had some decisive advantage over its regional neighbours: judging by the importance of metallurgy and mining activities in the Kura-Araxes world, this advantage could have been technological.
