The Chrysler Royal is an automobile which was produced by Chrysler Australia from 1957 to 1963. After investing in tooling to stamp body panels for the 1954 P25 series Plymouth locally, and with Chrysler headquarters in Detroit unwilling to assist in the costs of retooling for the new US models, Chrysler Australia made the decision to develop their own range, using as much of the existing tooling as possible, whilst also realising that the new car had to appear as different as possible. The doors and basic structure of the P25 sedan was retained, and with input from Australian and American Chrysler designers, the 1955 US Plymouth front sheetmetal was adapted to the P25 body and the rear quarter panels redesigned. They also added a wraparound rear windscreen, which caused development problems with Pilkington Glass, the Australian suppliers, who struggled to get the correct curved shape.

FCA Australia, known unofficially as Chrysler Australia or Stellantis Australia, is the official Stellantis subsidiary in that country, operating as distributor of Chrysler, Jeep, Dodge, Abarth, Alfa Romeo and Fiat vehicles. However, there had previously been a "Chrysler Australia Ltd" which had operated as a vehicle manufacturer in Australia from 1951 until 1980, and was subsequently taken over by Mitsubishi Motors Australia.
