The Opel Commodore is an executive car (E-segment) produced by Opel from 1967 to 1982. It is the six-cylinder variant of the Rekord with styling differences. The Commodore nameplate was used by Opel from 1967 to 1982. However, its nameplate/lineage continued until 2020 with the Australian Holden Commodore. The last generation was sold in the United Kingdom primarily as the Vauxhall Viceroy although Opel models were also sold.

Opel Automobile GmbH, usually shortened to Opel, is a German automobile manufacturer which has been a subsidiary of Stellantis since 16 January 2021. It was owned by the American automaker General Motors from 1929 until 2017 and the PSA Group prior to its merger with Fiat Chrysler Automobiles to form Stellantis in 2021. Most of the Opel lineup is marketed under the Vauxhall Motors brand in the United Kingdom since the 1980s. Some Opel vehicles were badge-engineered in Australia under the Holden brand until 2020, in North America and China under the Buick, Saturn, and Cadillac brands, and in South America under the Chevrolet brand.
