Kowdiar Palace (Malayalam: കവടിയാര് കൊട്ടാരം) in Trivandrum, Kerala, India was built in 1934 by Maharajah Sree Chithira Thirunal, on the occasion of the Pallikettu (wedding) of his only sister, Maharani Karthika Thirunal Lakshmi Bayi with Lt. Col. G. V. Raja. After the Constitutional Amendment of 1971, the properties and estates of the royal family were partitioned and divided equally among the branches of the two Travancore Queens, Sethu Lakshmi Bayi and Sethu Parvathi Bayi. This Palace belongs to the heirs of Sethu Parvathi Bayi as it was built by her son Maharajah Sree Chithira Thirunal.
Kowdiar Palace's architectural work is famous and has over 150 rooms. The entry to this palace is restricted as it is the private residence of the royal family settled in Thiruvananthapuram .
