The London Underground 1935 Stock was an experimental train design by Metropolitan Cammell in London. Twelve two-car units, marshalled into four six-car trains, were built. They served as the prototypes for the later 1938 Stock.

Metro-Cammell, formally the Metropolitan Cammell Carriage and Wagon Company (MCCW), was an English manufacturer of railway carriages, locomotives and railway wagons, based in Saltley, and subsequently Washwood Heath, in Birmingham. The company was purchased by GEC Alsthom in May 1989; the Washwood Heath factory closed in 2005 and was demolished in early 2019.
