John Marshall (1756–1824) was a London publisher who specialized in children's literature, chapbooks, educational games and teaching schemes. He called himself the "Children's Printer" and children his "young friends". He was pre-eminent in England as a children's book publisher from about 1780 to 1800. After 1795, he became the publisher of Hannah More's Cheap Repository Tracts, but a dispute with her led to him issuing a similar series of his own. About 1800 Marshall began publishing a series of miniature libraries, games and picture books for children. After his death in July 1824, his business was continued either by his widow or his unmarried daughter, both of whom were named Eleanor.

The Cheap Repository Tracts consisted of more than two hundred moral, religious and occasionally political tracts issued in a number of series between March 1795 and 1817, and subsequently re-issued in various collected editions until the 1830s. They were devised by Hannah More and intended for sale or distribution to literate poor people, as an alternative to what she regarded as the immoral traditional broadside ballad and chapbook publications. The tracts proved to be enormously successful with more than two million copies sold or distributed during the first year of the scheme.
