Vandavasi (formerly anglicised as Wandiwash[2]) is a Municipality and Taluk in the Tiruvannamalai district of the Indian state of Tamil Nadu.

Vandavasi town is also the largest manufacturer of kora artefacts including mats, shawls and vessels.

Wandiwash was the site of a decisive battle in the 18th century Carnatic Wars between France and the British Empire for control over south Asia.

The Battle of Wandiwash was a watershed moment in Indian history as it cemented British supremacy in India.

The Nayak of Vandavasi, a vassal of the Vijaynagar Empire, was instrumental in helping the British secure a land grant for Chandragiri Fort on which to build the city of Madras (modern day Chennai).
