Sieur de Bruno was a French adventurer and diplomat of the 18th century. He took an important role in developing French influence in Burma, and in leading French efforts at supporting the Mons during their conflicts against the Burmese. The Governor-General of French India Joseph François Dupleix had started to show interest in Burma since 1727, on account of the country's abundance in teak and crude oil. As a result, a French shipyard was established in the city of Syriam in 1729, building ships for Pondicherry. The shipyard was abandoned in 1742 due to the revolt of the Mon.
