Joseph Sabin (9 December 1821—5 June 1881) was a Braunston, England-born bibliographer and bookseller in Oxford, Philadelphia, and New York City.

[1][2] He compiled the "stupendous" multivolume Bibliotheca Americana: A Dictionary of Books Relating to America, considered a "bibliophilic monument;"[3] and published the American Bibliopolist, a trade magazine.

[4][5] Sabin was apprenticed to a bookdealer in Oxford in 1821 to learn bookbinding and established a partnership as a bookseller.

In 1850 he worked in New York for the auction firm, Cooley and Kees as a cataloger and then at Bangs, Brothers & Co. where he conceived the idea of identifying books related to Americana.

[13] At the sale of the library of the musicologist and rare book collector, Edward Francis Rimbault, in 1877, Sabin served as an agent for the banker and collector, Joseph W. Drexel, in his large purchase of portions of the 1877 auction, held in London from July 31 to August 7.
