Vaisigano is a political district at the western tip of Savai'i island in Samoa.

Within the district is the village of Vaisala whose chief Va'ai Kolone became the Prime Minister of Samoa twice in the 1980s.

There is a conservation area with a turtle habitat at the village of Auala and a rainforest reserve in Falealupo at the westernmost tip of the island.

Vaisigano district has strong links to the Tonumaipe'a chiefly title[2] and at a national level, the TuiA'ana.
