Thiruvithamcode (also spelled Thiruvithancode), is a small panchayat town located in the Kanyakumari district of the Indian state of Tamil Nadu.

Nanjilnadu, which is the present Agasteeswaram and Thovalai taluks of the Kanyakumari district, was under the rule of Cheras.

The annexation commenced by Veera Kerala Varma was to a large extent continued by his successors and completed by 1115 A.D. For about four centuries, Venad was ruled by kings.

He defeated the forces of the Dutch East India Company under Eustachius De Lannoy in 1741 at the Battle of Colachel.

The people of Agasteeswarem, Thovalai, Kalkulam and Vilavancode Taluks, which formed the southern divisions of the former Thiruvananthapuram District, were predominantly Tamil-speaking and a popular agitation for merging the Tamil-speaking majority areas of Southern Travancore to Madras State (now Tamil Nadu) was started during this period and was intensified under the leadership of M.A.

Accordingly, the States Reorganisation Act of 1956 was passed and the Kanyakumari District was formed on 1 November 1956, annexing the four Taluks of Southern Travancore namely Agasteeswarem, Thovalai, Kalkulam.
