The Federation of British Industries (FBI) was an employers' association in the United Kingdom.
Founded by the Midlands industrialist Dudley Docker in 1916 as the United British Industries' Association, but renamed later that same year, it was initially composed of 124 firms which each gave £1,000 for its foundation.
The FBI never took part in labour relations but was progressively involved in tariff reform.
It slowly gathered other regional and overseas organisations and was incorporated by Royal Charter in 1923.
It was by far the biggest organisation of the three, composed of about 9,000 individual firms and 272 trade associations by 1964.
