Puszcza Biała (, White Wilderness) is the name given to the forest that extends in Poland from Pułtusk to Ostrów Mazowiecka. It is part of the Mazovian lowlands and consists of small trees, mostly pine. The White Wilderness (Puszcza Biała) is usually associated with the Green Wilderness (Puszcza Zielona), and together the two forests are often referred to as the Kurpie Forest (Puszcza Kurpiowska) because the two forests were populated by inhabitants who, over the centuries of isolation, developed a unique culture of their own, called Kurpie.
