比亚沃维耶扎原始森林（白俄罗斯语：Белавеская пушча 波兰语：Puszcza Białowieska）位于布列斯特以北70公里，横跨白俄罗斯及波兰边境，是欧洲现存唯一的原始森林。

这个联合国教育科学文化组织世界遗产及生态保护区位于白俄罗斯西南部布列斯特州及格罗德诺州境内。波兰为了这个森林设立了比亚沃维耶扎国家公园，占地超过100平方公里。白俄罗斯则设立的生态保护区占地1771平方公里。

2014年对该世界遗产项目做了一些变动，波兰方面增加了近45000公顷，白俄罗斯方面减少了5000公顷左右，总共141885公顷，并将项目名称从“别洛韦日斯卡亚原始森林/比亚沃维耶扎森林”（Belovezhskaya Pushcha / Białowieża）更改为“比亚沃维耶扎原始森林”（Białowieża Forest）。

Białowieża Forest (Belarusian:Белавежская пушча, Biełaviežskaja Pušča; Polish:Puszcza Białowieska  Polish pronunciation: [ˈpuʂt͡ʂa ˌbʲawɔˈvʲɛska]; Russian:Беловежская пуща, Belovezhskaya Pushcha) is one of the last and largest remaining parts of the immense primeval forest that once stretched across the European Plain. The forest is home to 800 European bison, Europe's heaviest land animal. UNESCO’s Man and the Biosphere Programme (MAB) designated the Polish Biosphere Reserve Białowieża in 1976 and the Belarusian Biosphere Reserve Belovezhskaya Puschcha in 1993. In 2015, the Belarusian Biosphere Reserve occupied the area of 216,200 ha (2,162 km; 835 sq mi), subdivided into transition, buffer and core zones. The forest has been designated a UNESCO World Heritage Site and an EU Natura 2000 Special Area of Conservation. The World Heritage Committee by its decision of June 2014 approved the extension of the UNESCO World Heritage site “Belovezhskaya Pushcha/Białowieża Forest, Belarus, Poland”, which became “Białowieża Forest, Belarus, Poland”. It straddles the border between Poland (Podlaskie Voivodeship) and Belarus (Brest and Grodno voblasts), and is 70 kilometres (43 miles) north of Brest, Belarus and 62 kilometres (39 miles) southeast of Białystok, Poland. The Białowieża Forest World Heritage site covers a total area of 141,885 ha (1,418.85 km; 547.82 sq mi). Since the border between the two countries runs through the forest, there is a border crossing available for hikers and cyclists.
