Passo Tanarello (in Italian) or Pas du Tanarel (in French) at 2,042 m is a mountain pass in the Ligurian Alps.

Tanarello is the diminutive form of Tanaro, the main right-bank tributary of the River Po.

It connects the basins of the Ligurian Sea (south of the pass) and the River Po.

Up to World War II, the pass was totally in Italian territory, but due to the Paris Peace Treaties signed in February 1947, it is now on the border between Italy and France.

[4] The pass is easily accessible by walking and mountain bike by following the old military road.
