Bhuvanaikabahu I was King of Dambadeniya in the 13th century, who ruled from 1271 to 1283.

He succeeded his brother Vijayabahu IV as King of Dambadeniya and an Interregnum of 19 years is thought to have occurred after his death.

His nephew Parakkamabahu III ruled from Polonnaruwa, and was not formally considered as a King of Dambadeniya.

Historical chronicles record that king Bhuvanaikabahu sent an embassy to the Mamluk Sultanate in early 1283 with the aim of forming an alliance.
