Thoothoor is a coastal village located in the Kanyakumari district in southern Tamil Nadu, India.

The name is derived from the white sands everywhere that covered much of the area, at a time when people occupied a small settlement and much of the land was vacant.

The Catholic Church plays a conspicuous role in the day-to-day life of the fishermen of Thoothoor village.

The event culminated in the works of St. Francis Xavier, who is said to have converted 10,000 Mukkuva fishermen living in thirteen villages along the coast (from Pallam to Poovar—Neerody, Marthandanthurai, Vallavilai, Eraviputhenthurai, Thoothoor, Poothurai, Thengapattanam, Enayam, Midalam, Vaniyakudy, Colachel, Kadiapattanam, Muttom and Pallam) in December 1544.

In 1952 all the coastal Churches from Pallithura to Erayumanthurai were temporarily added to the Roman Catholic Archdiocese of Trivandrum or Thiruvananthapuram Diocese.

Thoothoor is geographically located in Killiyoor Taluk, Kanyakumari District, Tamil Nadu, India.

Thoothoor is almost exclusively a fishing village, even though a little group of people are involved in agriculture, especially in coconut plantations, besides their primary occupation in other professions.

All such people are trained professionals, graduates, and a few PhD holders in mathematics, history, Tamil and physics.
