Bhuvanekabahu VI (Sapumal Kumaraya) (Sinhala:සපුමල් කුමාරයා) or Chempaha Perumal (died 1480) was by self admission an adopted son of Parakramabâhu VI whose principal achievement was the conquest of Jaffna Kingdom in the year 1447 or 1450. He ruled the Kingdom for 17 years when he was apparently summoned to the south after the demise of his adopted father. According a primary source Rajavaliya, he killed the grand son of Parakrama Bahu VI namely Vira Parakrama Bahu or Jaya Bahu (1468 – c. 1470) but Do Couto, however, who was well-informed, says after a few years' reign the king died and his half-witted son was put on the throne by his aunt, who two years later finding herself unable to rule sent for Sapumal Kumaraya from Jaffna.
