The Opel Commodore was 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 continues 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.

The Opel Commodore A was manufactured from 1967 to 1971, based on the Rekord C. After having offered a Rekord-6 powered by a 2.6 L 6-cylinder engine since March 1964, Opel in February 1967 launched the Commodore as a faster up-market version of the Rekord. The Commodore was initially available with the known A 2.2-litre six or a larger 2.5 L engine developing 115 PS (85 kW) with a single carburettor. Body styles comprised a two-door or four-door notchback saloon and a two-door hardtop/fastback coupé. In September 1967 the sporty Commodore GS offering 130 hp (96 kW) from a double-carburettor 2.5 L-six was introduced.

For model year 1969, the carryover 2.2-litre six was dropped and the optional 2-speed Powerglide automatic was abandoned in favor of Opel's new 3-speed automatic transmission.

From September 1969, the base 2.5 L-engine was pumped up to 120 PS (88.3 kW; 118.4 hp); at the same time, both remaining engines received hydraulic lifters for smoother running, a new exhaust system and six camshaft bearings. The handbrake lever was moved from its position under the dash to a location between the front seats and the fuel tank was enlarged from 55 to 70 litres.

An even more sporty model than the GS, the Commodore GS/E, debuted in March 1970. It had a 2.5 L engine equipped with Bosch D-jetronic fuel injection system developing 150 PS (110 kW), which gave the car a top speed of 197 km/h (123 mph). The Commodore GS/E also had a career in motorsports, with a car prepared by Steinmetz. In April 1970 a Commodore with a detuned and carburetted 2.8 L-six giving 145 PS (106.6 kW; 143.0 hp) followed (GS 2800).
