The Lengyel culture is an archaeological culture of the European Neolithic, centered on the Middle Danube in Central Europe. It flourished from 5000 to 4000 BC, ending with phase IV, e.g., in Bohemia represented by the 'Jordanow/Jordansmühler culture'. It is followed by the Funnelbeaker culture/TrB culture and the Baden culture. The eponymous type site is at Lengyel in Tolna county, Hungary.

The European Neolithic is the period from the arrival of Neolithic technology and the associated population of Early European Farmers in Europe, c. 7000 BC until c. 2000–1700 BC. The Neolithic overlaps the Mesolithic and Bronze Age periods in Europe as cultural changes moved from the southeast to northwest at about 1 km/year – this is called the Neolithic Expansion.
