Tanarello is the diminutive form of Tanaro, the main right-hand tributary of river Po.

The river rises between Monte Saccarello and Monte Tanarello as a stream named Tanarello and becomes Tanaro after receiving the waters of another stream called Negrone.

[3] The mountain up to World War II was totally belonging to Italy but, following the Paris Peace Treaties, signed in February 1947, is now shared between Italy and France.

Its Italian side belongs to the province of Cuneo, in Piedmont (Tanaro valley), and the French one to Alpes-Maritimes, in the Provence-Alpes-Côte d'Azur (Roya valley).
