Henry Thomas Colebrooke FRS FRSE FLS (15 June 1765 – 10 March 1837) was an English orientalist and botanist.

He wrote Remarks on the Husbandry and Commerce of Bengal,[3] which was privately published in 1795, by which time he had transferred to Purnia.

Also in 1805, Lord Wellesley appointed him honorary professor of Hindu law and Sanskrit at the college of Fort William.

[2][4][5][6] After eleven years of residence in India, Colebrooke began the study of the Sanskrit language; and to him was entrusted the translation of the major Digest of Hindu Laws, a monumental study of Hindu law which had been left unfinished by Sir William Jones.

During his residence at Calcutta he wrote his Sanskrit Grammar (1805), some papers on the religious ceremonies of the Hindus, and his Essay on the Vedas (1805), for a long time the standard work in English on the subject.
