The Gumelnița–Kodžadermen-Karanovo VI complex was a Chalcolithic cultural complex of the fifth millennium BC located in the eastern Balkans, comprising the Gumelnița, Kodžadermen and Karanovo cultures. It is also aggregated with the Varna culture. It formed part of the broader cultural complex known as Old Europe. Gumelnița–Kodžadermen-Karanovo VI evolved out of the earlier Boian culture and phase V of the Karanovo culture. From c. 4000 BC Gumelnița–Kodžadermen-Karanovo VI was replaced by the Cernavodă culture.
