Kerala, southwestern coastal state of India. It is a small state, constituting only about 1 percent of the total area of the country.

It is bordered by the states of Karnataka (formerly Mysore) to the north and Tamil Nadu to the east and by the Arabian Sea to the south and west; it also surrounds Mahe, a segment of the state of Puducherry, on the northwestern coast. The capital is Thiruvananthapuram (Trivandrum).
