Deighton, Bell, & Company was a British firm of booksellers and publishers located in Cambridge, England.

[4] The firm was founded in 1778 by John Deighton (1748-1828), a master bookbinder, and was located in "narrow, early eighteenth-century premises"[1] at the corner of Green and Trinity Streets, Cambridge, which would be the location of the firm for its entire existence.

[2] He also gained a reputation as a book retailer with a "remarkable ability to supply foreign books, even in time of war",[5] which was particularly important to the university's library in that era before the introduction of the Uniform Penny Post throughout the United Kingdom and before the coming of the railways to all parts of the country.

[7][8] In 1876 it was publishing, jointly with George Bell & Sons and Whittaker & Co., a number of textbook series for the secondary school and university markets.

[2] In 1987 Deighton, Bell, and Co. was acquired by Heffers, which was in turn taken over by the academic book retailer and library supply service, Blackwell's.
