Ormando W. Gray (fl. 1860 – 1880) was a mid to late 19th century map publisher with offices in New York City, Philadelphia, PA, and Danielsonville, Connecticut. He was trained a civil engineer and surveyor. Gray's first commercial atlas was an 1869 survey of Windhamd and Toland counties, Connecticut. His most important work seems to have been done in conjunction with other, more prominent map publishers, including Henry Walling and G.W. and C.B. Colton. Gray is best known for his state and county atlases, though did, with his sons, also independently issued at least two national atlases in the late 1870s.
