Kowdiar Palace is the official residence of the Travancore Royal Family, situated in Thiruvananthapuram, Kerala, India.

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.

The entry to this palace is restricted as it is the private residence of the royal family settled in Thiruvananthapuram.
