The Mors automobile factory was an early French car manufacturer. It was one of the first to take part in automobile racing, beginning in 1897, due to the belief of the company founder, Émile Mors, in racing's technical and promotional benefits. By the turn of the century, automobile racing had become largely a contest between Mors and Panhard.

Mors was one of the first automobiles to use the V engine configuration. The Mors 60 horsepower Grand Prix car was powered by a 10 liter V4 side valve engine, with magneto ignition, which could reach 950 rpm. The car had a steel chassis and a four-speed transmission which drove the rear wheels via chain drive, and rear-wheel brakes. In 1902, Mors added dampers (shock absorbers) to their cars, which represented a great leap forward given the quality of the roads and racetracks at the time. With this car, Henri Fournier was able to win the highly significant Paris-Berlin race, with the drive chain breaking immediately afterwards.

Mors ended racing in 1908. Plans to return to auto racing were cancelled due to World War I.

André Citroën became chairman of Mors in 1908 and restored the company's viability. In 1925, Citroën bought Mors outright and closed it down, using its factory for the production of his Citroën automobiles.

The marque was resurrected briefly when a few small electric cars were made during World War II by a subsidiary electrical company of Émile Mors.
