Raja Bhuvan Mohan Roy (1876–1934) was the Chief of the Chakma Circle in the Chittagong Hill Tracts from 1897 until 1933.

[1][2] After the death of his father in 1885, the Court of Wards assumed the administration of the estate and the Chakma Circle, Bhuvan Mohan being a minor.

[3] Bhuvan Mohan Roy was installed as Chief of the Chakma Circle on 7 May 1897, in recognition of which he received the personal title of Raja.

[2] James Philip Mills, an Indian Civil Service officer tasked in 1926–1927 with investigating how the Bengal Government could best use the Chittagong Hill Tracts Chiefs in the administration, wrote of him: Raja Bhuban Mohan Ray is in character both obstinate and weak ...

I can find no record that he ever on any occasion aided Government with any valuable advice ... His love of Bengali culture has antagonised the respectable and conservative elements in the tribe.
