Thomas R. Johnson (f. c. 1878 - 1890) was a map publisher in Boston, Massachusetts. His two known works include an 1884 'Section Map and Index of New England States' (based on a map by G.W. and C.B. Colton) and an 1881 'Section Map and Street Index of the city of Boston' in 1881 (engraved and printed by George H. Walker and Co., an early work from the firm which became prolific in the following decades). Otherwise, little is known about Johnson's life and work; Boston city directories throughout the late 1870s and 1880s list Thomas R. Johnson as either a salesman or bookkeeper.
