The Azibo River is a Portuguese river in the Douro River basin. It has its source in the Nogueira mountains, near the place of Rebordainhos, Bragança Municipality, in the northeast of Portugal. Along its 50 kilometres of length, it crosses the Macedo de Cavaleiros Municipality, where in 1982 an earthfill dam was built near Santa Combinha place (Azibo Reservoir). The Azibo river has its mouth near the place of Lagoa (Macedo de Cavaleiros Municipality), on the right bank of Sabor River, which is a tributary of Douro River.
