Benjamin Warner (fl. c. 1800 - 1830) was an American bookseller and publisher based in Philadelphia during the first half of the 19th century. Waner was a Pennsylvania Quaker who partnered with Jacob Johnson, a bookseller, printer, and inkmaker to produce numerous imprints. He maintained a location at 147 High Street (147 Market St) Philadelphia, as well as shops in Richmond, Virginia and Charleston, South Carolina. His apprentices included John Grigg, later known for medical imprints.
