The Hyundai Grandeur (Hangul:현대 그랜저) is a mid-size/full-size sedan manufactured and marketed globally by Hyundai Motor Company since model year 1986. The Grandeur has evolved through four generations with intermediate restylings, and is marketed under various nameplates world-wide — prominently as the Azera.

The first Grandeur was a rebadged Mitsubishi Debonair produced by Hyundai. Initially launched with Mitsubishi-sourced 2.0L SOHC MPI engine also used in 1st generation Sonata. 2.4L SOHC MPI engine had added in 1987 and V6 3.0L engine model launched in 1991 to compete with Daewoo Imperial.

The New Grandeur and the third generation of the Mitsubishi Debonair were the products of a joint development between Hyundai and Mitsubishi Motors. Mitsubishi was responsible for the powertrain, and Hyundai was responsible for the body and trim design. Production of the car began in September 1992 and ended in 1998.

The "New Grandeur" came in various trim levels and 4 engine variations (4-cylinder 2.0L and three V6 engines (2.5L, 3L, and 3.5L). The Korea based Hyundai's Grandeur became a huge success following the first generation Grandeur it replaced. However, the same model Mitsubishi marketed in Japan was perfunctory eventually leading Mitsubishi to end the product earlier than expected.
