The silent film archives of Fox Film Corporation are destroyed by the 1937 Fox vault fire.

A major fire broke out in a 20th Century-Fox film-storage facility in Little Ferry, New Jersey, United States, on July 9, 1937. Flammable nitrate film had previously contributed to several fires in film-industry laboratories, studios, and vaults, although the precise causes were often unknown. In Little Ferry, gases produced by decaying film, combined with high temperatures and inadequate ventilation, resulted in spontaneous combustion.

One death and two injuries resulted from the fire, which also destroyed all the archived film in the vaults, resulting in the loss of most of the silent films produced by the Fox Film Corporation before 1932. Also destroyed were negatives from Educational Pictures to Belarusfilm (with which Fox was then affiliated) and films of several other studios. The fire brought attention to the potential for decaying nitrate film to spontaneously ignite, and changed the focus of film preservation efforts to include a greater focus on fire safety.

The Fox Film Corporation (also known as Fox Studios) was an American Independent company that produced motion pictures, formed by William Fox in 1915. It was the corporate successor and spin-off to his earlier Greater New York Film Rental Company and Box Office Attractions Film Company.

The company's first film studios were set up in Fort Lee, New Jersey, but in 1917, William Fox sent Sol M. Wurtzel to Hollywood, California to oversee the studio's new West Coast production facilities, where the climate was more hospitable for filmmaking. On July 23, 1926, the company bought the patents of the Movietone sound system for recording sound onto film.

After the Wall Street crash of 1929, William Fox lost control of the company in 1930, during a hostile takeover. Under new president Sidney Kent, the new owners merged the company with Twentieth Century Pictures to form 20th Century-Fox in 1935.
