Thomas James Cobden-Sanderson (2 December 1840 – 7 September 1922) was an English artist and bookbinder associated with the Arts and Crafts movement.
He was born in Alnwick, Northumberland, as Thomas James Sanderson. Sanderson attended many schools including the Royal Grammar School Worcester before entering Owen's College (Manchester University) and then Trinity College, Cambridge to study law. He left without taking a degree, and entered Lincoln's Inn as a barrister. In 1882 he married (Julia Sarah) Anne Cobden (1853–1926), a daughter of Richard Cobden, and they both took the surname Cobden-Sanderson.
As a friend of William Morris, Cobden-Sanderson was involved with the Arts and Crafts ideology, and during a dinner party with the Morrises he was persuaded by Morris's wife Jane Burden to take up book-binding. In about 1884 he opened a workshop, abandoning his law practice. In 1887 Cobden-Sanderson suggested a new group be named the "Arts and Crafts Exhibition Society," and in so doing gave the movement its name. By 1900 he had established the Doves Press in Hammersmith, London, naming it after an old pub next door, The Dove. Emery Walker became a partner in 1900 and oversaw the creation of the Doves Type used for all of their books. They produced a number of letterpress books, including the famous five-volume Doves Bible.
