Wellington Williams (1814 - July 8, 1875) was an American engraver based in Germantown, Philadelphia. Williams was born in Bath, England. He emigrated to England as a young man, establishing himself in Philadelphia as a map and line engraver. He most notably engraved the maps for both Samuel Augustus Mitchell and his son, Samuel Augustus Mitchell Jr. There is some evidence that Williams resented the relationship and derived little profit from the success of two Mitchell atlases. He also engraved for William C. Woodbrid and D. Appleton. In addition, Williams also published several maps and views under his own imprint. His home was located at 1857 Mervine Street, 20th Ward, Philadelphia. His offices were located in Philadelphia, on 5th Street, below Chestnut. He was interred at the Laurel Hill Cemetery, Philadelphia.
