The Cortaillod culture is one of several archaeologically defined cultures belonging to the Neolithic period of Switzerland.

The Cortaillod Culture in the west of the region is contemporary with the Pfyn Culture in the east and dates from between 3900-3500 BCE.

The Classic Cortaillod Culture of the western Alpine foreland and the Early Cortaillod Culture of central Switzerland predate this at 4300-3900 BCE.Evidence such as higher frequencies of dog bones and pendants made from dog metapodials suggests a special relationship between dog and man during the later part of this period in the western part and the early Horgen culture in the eastern part of the Alpine foreland.
