Berga Kulle Nature Reserve (Swedish: Berga Kulle naturreservat) is a nature reserve in Södermanland County in Sweden.

The nature reserve consists of a rocky plateau or hill and its surroundings.

Large patches of bedrock dominate the hill, where Scots pine grow, often in the form of krummholz.

In the south-western part of the nature reserve, moraine characterises the geology, and here the pine trees grow taller and stronger.
