Samuel Eleazer Mann (April 10, 1853 - September 14, 1930) was a Methuen, Massachusetts, based cartographer who produced large format missionary field maps on cloth for the American Baptist Missionary Union (A.B.M.U). Most of Mann's maps appear to have been one-offs designed on cloth using Diamond Dyes, India ink, and stencils. The maps were made to order as field documents for various Baptist missionary societies, most particularly the A.B.M.U. The archives of Mount Holyoke College identify one such map, some 13 feet wide, acquired by the Student Volunteer Band.
