The 6th millennium BC spanned the years 6000 BC to 5001 BC (c. 8 ka to c. 7 ka). It is impossible to precisely date events that happened around the time of this millennium and all dates mentioned here are estimates mostly based on geological and anthropological analysis. The only exceptions are the felling dates for some construction timbers from Neolithic wells in Central Europe.

This millennium is reckoned to mark the end of the global deglaciation which had followed the Last Glacial Maximum and caused sea levels to rise by some 60 m (200 ft) over a period of about 5,000 years.
