Wai (ISO: Vāī; Pronunciation: [ʋaːi] listenⓘ) is a town in Satara district of Maharashtra state in India.

Locally prominent families such as the Raste, Ranade, and Phadnavis built several architecturally significant temples in Wai.

The 400-year-old Mandhradevi Kalubai temple is about 12 kilometres (7.5 mi) from Wai on a hill 718 metres (2,356 ft) above sea level.

The 17th-century warlord Afzal Khan, representing Ali Adil Shah II of the Bijapur Sultanate, is said to have made his first halt here on his way to the fort Pratapgad of the Maratha ruler Chhatrapati Shivaji Maharaj.

Waters held by Dhom and Balakwadi dams, west of Wai taluka, surround the region's remaining small villages.

Situated on the Mahad-Pandharpur State Highway, Wai is a major city on the way to the hill stations of Mahabaleshwar and Panchgani.

When warlord Afzal Khan set out from Wai to attempt to defeat Chhatrapati Shivaji Maharaj, Shendye Shāstri of Wai prayed to the Krishna River for Chhatrapati Shivaji Maharaj's victory, sparking the Krishnamai festival.

The annual fairs, Yatras/Jatras, began with the Yatra of Mahalaxmi of Bhuinj, Jamb, Kikli and Belmachi on Dassraa.

Yatras in the Wai taluka include Mandhardevi, Bagad of Bavdhan, Kavathe, Kalambhe and Surur.
