Mulliners Limited of Birmingham was a British coachbuilding business in Bordesley Green, Birmingham with factories in Bordesley Green Road and in Cherrywood Road. It made standard bodies for specialist car manufacturers. In the 19th century there were family ties with founders Mulliners of Northampton and the businesses of other Mulliner brothers and cousins but it became a quite separate business belonging to Herbert Mulliner.
A Northampton coach building family founded this business in Leamington Spa for the prosperous custom attracted to the newly fashionable spa town early in the 19th century. Direct ownership and control by Mulliner family interests was lost in 1903 when it was sold to Charles Cammell, which then merged into Cammell Laird. H H Mulliner ceased to be a main-board director of Cammell-Laird in 1909. Mulliners Limited continued under various ownerships until the end of 1960, when Standard-Triumph International closed it down.
