Cisano sul Neva (Ligurian: Cixan) is a comune (municipality) in the Province of Savona in the Italian region Liguria, located about 70 kilometres (43 mi) southwest of Genoa and about 35 kilometres (22 mi) southwest of Savona.

The comune gets its name from the Neva, a stram flowing down from the Ligurian Alps and crossing its territory.

The town was part of the Marca Aleramica in the 10th century, and in 1091 it became a possession of Boniface del Vasto.

Later it was under the Clavesana family, and in 1274 it was acquired by the commune of Albenga, which fortified it.

Cisano is connected to Albenga and Garessio by the Provincial Road 582.
