Jeyaveera Cinkaiariyan (Tamil: செயவீர சிங்கையாரியன்) (died 1410??) was the Aryacakravarti king of the Jaffna Kingdom in modern-day northern Sri Lanka, who had a military confrontation with a southern chief known as Alagakkonara. According to traditional sources, Alagkkonara defeated Jeyaveera's naval and land forces and assumed royal power in the southern Gampola Kingdom. Later, King Harihara II's brother Yuvaraja Virupanna invaded Sri Lanka from Karnataka, defeated Alagkkonara and established a pillar of victory there.
