The Chiusella (Piedmontese: Ciusèila) is a 41-kilometre (25 mi) long river in the Piedmont region of Italy.

The Chiusella starts in the Graian Alps near Mount Marzo and Bocchetta delle Oche, a mountain pass connecting its valley with Val Soana.

Flowing initially from NW to SE it reaches Traversella and the permanently inhabited part of the valley.

In the territory of Issiglio it receives from the right side the waters of Torrente Savenca, its main tributary.

The Chiusella is then blocked by a dam forming the Lake Gurzia.
