Nagercoil ("Temple of the Nagas" Nagaraja Temple) is a town in the southernmost Indian district of Kanyakumari and a municipality and administrative headquarters of Kanyakumari District in Tamilnadu.

Known as the Granary of Travancore, Nagercoil not only served as the food basket of Kerala, but was also one among the important spice-trading centers in the kingdom of Travancore from the 14th century onward, and maintained a trade network with Arab merchants from the pre-Islamic era.

The architecture of Nagercoil consists of an eclectic combination of architectural styles, ranging from those that predate the creation of the town, from the early Dravidian architecture and Kerala Architecture, to English Gothic Revival, to the 21st century contemporary.

Tamil is the official language in Nagercoil and is spoken by the majority of the population here.

There are many schools and colleges in Nagercoil that are more than 100 years old, such as Scott Christian College (est 1809) and Scott Christian Higher Secondary School (est 1819).

Onam is a festival which is widely celebrated among the Malayalam-speaking population by drawing the `atha poo (flower decoration) in the floor.
