Riley was a British motorcar and bicycle manufacturer from 1890. Riley became part of the Nuffield Organization in 1938 and was merged into the British Leyland Motor Corporation in 1968. In July 1969 British Leyland announced the immediate end of Riley production, although 1969 was a difficult year for the UK automotive industry and many cars from Riley's inventory may have been first registered in 1970.

Today, the Riley trademark is owned by BMW.
