The Riley 4 / Sixty Eight and Riley 4 / Seventy Two are cars produced by BMC from 1959 to 1969, under the Riley marque. They are closely related to the Pinin Farina-designed MG Magnette Mark III and Wolseley 15/60 and the simpler Austin A55 Cambridge Mark II, Morris Oxford V pair, sharing the MG's rear styling and engine. This Riley was the most expensive car in that series.

The British Motor Corporation Limited (BMC) was a UK-based vehicle manufacturer, formed in early 1952 to give effect to an agreed merger of the Morris and Austin businesses.
