Polesia (Polesye) is a natural and historical region starting from the farthest edges of Central Europe and into Eastern Europe, stretching from parts of Eastern Poland, touching similarly named Podlasie, straddling the Belarus–Ukraine border and into western Russia.

The Polish part of the region includes the Polesie National Park (Poleski Park Narodowy), established 1990, which covers an area of 97.6 square kilometres (37.7 sq mi). This and a wider area adjoining it (up to the Ukrainian border) make up the UNESCO-designated West Polesie Biosphere Reserve, which borders a similar reserve (the Shatskiy Biosphere Reserve) on the Ukrainian side.
