MG Rover Group was a British carmaker that existed between 2000 and 2005. It was the last domestically owned mass-production car manufacturer in the British motor industry. The company was formed when BMW sold the car-making and engine manufacturing assets of the original Rover Group to Phoenix Venture Holdings in 2000.

The Rover Group plc was the British vehicle manufacturing conglomerate known as "BL plc" until 1986, which had been a state-owned company since 1975. It initially included the Austin Rover Group car business, Land Rover Group, Freight Rover vans and Leyland Trucks. The Rover Group also owned the dormant trademarks from the many companies that had merged into British Leyland and its predecessors such as Triumph, Morris, Wolseley, Riley and Alvis.
