The Comb Ceramic culture or Pit-Comb Ware culture, often abbreviated as CCC or PCW, was a northeast European culture characterised by its Pit–Comb Ware. It existed from around 4200 BCE to around 2000 BCE. The bearers of the Comb Ceramic culture are thought to have still mostly followed the Mesolithic hunter-gatherer lifestyle, with traces of early agriculture.

The Mesolithic or Middle Stone Age is the Old World archaeological period between the Upper Paleolithic and the Neolithic. The term Epipaleolithic is often used synonymously, especially for outside northern Europe, and for the corresponding period in the Levant and Caucasus. The Mesolithic has different time spans in different parts of Eurasia. It refers to the final period of hunter-gatherer cultures in Europe and the Middle East, between the end of the Last Glacial Maximum and the Neolithic Revolution. In Europe it spans roughly 15,000 to 5,000 BP; in the Middle East roughly 20,000 to 10,000 BP. The term is less used of areas farther east, and not at all beyond Eurasia and North Africa.
