Kampinos Forest (Polish: Puszcza Kampinoska) is a large forest complex located in Masovian Voivodeship, west of Warsaw in Poland.
It covers a part of the ancient valley of the Vistula basin, between the Vistula and the Bzura rivers. The forest began to form 14-11,000 years ago, at the very end of the Last Glacial Period.
Once a forest covering 670 km2 of central Poland, it currently covers roughly 240 km2. In its present day form, most of the woodland is no longer old-growth forest but rather the remainders of a once-managed forest which is now left to grow on its own, with little human intervention.
