De Joux was a New Zealand car manufacturer based in Auckland, North Island, operating under the name Ferris De Joux Design.
The company was known for the De Joux GT, a sports coupé created by designing a fibreglass body to mate with the floorpan, bulkhead, and sills of the Mini. Compared with the standard Mini, the De Joux GT was significantly lower, wider, and longer, yet it weighed 46 kg less than its donor car.
The only mechanical alteration made to the design was the relocation of the radiator to the front of the car, which allowed for a lower bonnet line.
