The Wright Model B is an early pusher biplane designed by the Wright brothers in the United States in 1910. It was the first of their designs to be built in quantity. Unlike the Model A, it featured a true elevator carried at the tail rather than at the front. It was the last Wright model to have an open-frame tail. The Model B was a dedicated two-seater with the pilot and a passenger sitting side by side on the leading edge of the lower wing.

Besides their civil market, the Wrights were able to sell aircraft to the Aeronautical Division, U.S. Signal Corps (S.C. 3, 4, and 5[1]) and to the United States Navy as hydroplanes (AH-4, -5-, and -6), in which services they were used as trainers. Furthermore, the Wrights were able to sell licenses to produce the aircraft domestically (to the Burgess Company and Curtis, which designated it Model F; not to be confused with the Wright Model F, an unrelated Wright design), as well as in Germany. The deal with Burgess was the first license-production of aircraft undertaken in the United States and most of the approximately one hundred Model Bs produced were actually built by Burgess.

Development continued as the Model EX. Burgess also planned a refined version as the Model G (not to be confused with the Wright Model G, an unrelated Wright flying boat), but this was never built.
