Cankili I (Tamil: சங்கிலியன்) (died 1565), also known as Segarasasekaram (Jaga Rajasekharam), is the most remembered Jaffna kingdom king in the Sri Lankan Tamil history. He was active in resisting Portuguese colonial inroads into Sri Lanka. He inherited his throne via palace intrigues in which a number of heirs died under mysterious circumstances. Ultimately, he was removed from power by a local uprising that led to his son Puviraja Pandaram taking nominal power from him.
