Keerimalai Naguleswaram temple (), historically known also as the Thirutambaleswaram Kovil of Keerimalai, is a famous Hindu temple in Keerimalai, located north of Jaffna, Northern Province, Sri Lanka in the suburb of Kankesanthurai. One of the oldest shrines of the region, it is the northernmost of the island's Pancha Ishwarams of Lord Siva, venerated by Hindus across the world from classical antiquity. Hindus believe its adjacent water tank, the Keerimalai Springs, to have curative properties, which irrigation studies attribute to high mineral content sourced from underground.
