Thoothukudi District is one of the 38 districts of Tamil Nadu state in southern India. The district was formed by bifurcation of Tirunelveli district on 20 October 1986. Thoothukudi is the district headquarters and largest city of the district. The district is known for fishing as well as pearl cultivation, with an abundance of pearls being found in the seas offshore. Thoothukudi district has many historical sites such as Adichanallur and the ancient trade port of Korkai.

Thoothukudi district is situated in the south-eastern corner of Tamil Nadu. It is bounded by the districts of Virudhunagar on the north, Ramanathapuram on the north-east, Tirunelveli on the west and south-west, Tenkasi on the north-west and Gulf of Mannar on the east and southeast. The total area of the district is 4,621 km (1,784 sq mi).

There are no large reservoirs in this district so the Papanasam and Manimuthar dams located in the Tirunelveli district in the Thamirabarani River's flow are the main sources of irrigation. Other than the Thamirabarani River, the river Vaipar in Vilathikulam taluk, the river Karumeni which traverses through Sathankulam, and Tiruchendur taluks, Palayakayal are all sources.
