The Pibor River (also called the River Pibor^[1]) is a river in eastern South Sudan, which defines part of South Sudan's border with Ethiopia. From its source near Pibor Post it flows north for about 320 kilometres (200 mi), joining the Baro River to form the Sobat River, which is a tributary of the White Nile.^[2]

The Pibor and its tributaries drain a watershed 10,000 km² (3,900 sq mi) in size. The river's mean annual discharge at its mouth is 98 m³/s (3,460 ft³/s).^[3]
