Parvati Puthannar (Malayalam: പാർവതി പുത്തനാർ) is a manufactured canal that runs through the west coast of the Thiruvananthapuram district.
It was named after Rani Parvathi Bai, who was the reigning queen of Travancore during the time it was created.
It was created primarily for connecting the Travancore capital to Kadinamkulam, the Vamanapuram River and finally to Kochi.
It starts from the Kadinamkulam Lake in the north and flows south-east, parallel to the Trivandrum coast.
