The Negrone is an 11 kilometres (6.8 mi) long stream principally in Italy that flows through the regions of Piedmont and Liguria. Rising at Cime de Missun in the Ligurian Alps of France, the river, alongside the Tanarello, forms the Tanaro river, itself a tributary of the Po.[1][2] The Negrone is known by several other names in different areas.[3]
