The Nurzec is a river in north-eastern Poland, a tributary of the Bug River. It flows through the geographical region known in Polish as Wysoczyzny Podlasko-Bialoruskie (the plateau of Podlaskie and Belarus). Administratively, it lies within Podlaskie Voivodeship and Masovian Voivodeship.
The 2102km2 drainage area of the Nurzec is contained within the mezoregions known as Równina Bielska (the Bielsk Plain) and Wysoczyzna Wysokomazowiecka (the High Masovian Plateau).
The Nurzec rises in swamps south-east of Czeremcha near Stawiszcze close to the border with Belarus. Its confluence with the Bug River is close to the village of Wojtkowice Stare just south of Ciechanowiec.
