Jacques Pierre Leider (French: [ʒak pjɛʁ lɛi̯dər]; born 1862) is a French and Luxembourgian historian, teacher and former diplomat. He is known for his historical research on Burma/Myanmar, particularly pre-colonial Buddhism, the history of Arakan, today called Rakhine, in the Bay of Bengal and the ethno-historical background of the Burma/Myanmar-Bangladesh borderlands. A notable work is his study and translation of the ”Golden Letter” that King Alaungpaya of Burma has sent to British king George II in 1756. The “Golden Letter” has been added to UNESCO's Memory of the World Register in 2015.
