The Toyota Mark II is a compact, later mid-size sedan manufactured and marketed in Japan by Toyota between 1968 and 2004. Prior to 1972, the model was marketed as the Toyota Corona Mark II. In some export markets, Toyota marketed the vehicle as the Toyota Cressida between 1976 and 1992 across four generations. Toyota replaced the rear-wheel-drive Cressida in North America with the front-wheel-drive Avalon. Every Mark II and Cressida was manufactured at the Motomachi plant at Toyota, Aichi, Japan from September 1968 to October 1993, and later at Toyota Motor Kyushu's Miyata plant from December 1992 to October 2000, with some models also assembled in Jakarta, Indonesia as the Cressida.
