Thambiluvil Kannaki Amman Kovil is one of the most significant Hindu temples in the Ampara District of Eastern Province, Sri Lanka. It is situated about 70 km south of Batticaloa town and 11 km south to Akkaraipattu. It is considered as one of the ancient temples of Mattakkalappu Desam made for Kannaki Amman, the heroine of the great Tamil epic Silappatikaram.

Kannaki Amman is the deified form of Kannagi, the heroine of the Tamil epic Cilappatikāram. She is primarily worshipped in Sri Lanka and Kerala, and in a minor way in few parts of Tamil Nadu. As a goddess of chastity, she is venerated by Indian Tamils and Malayalis, Sri Lankan Tamil Shaivites, and also by the Sinhalese Buddhists as Pattini Amma. In regional Hindu tradition, her tale is interpreted as the story of Durga demanding justice after the death of her husband, Kovalan, who is identified as a form of Shiva.
