The Triumph 2000 is a mid-sized, rear wheel drive automobile which was produced in Coventry by the Triumph Motor Company between 1963 and 1977. Larger-engined models, known as the Triumph 2.5 PI and Triumph 2500 were also produced from 1968.

The 2000 used the six-cylinder engine first seen in the Standard Vanguard at the end of 1960. However, the last of the six cylinder Vanguards had applied a compression ratio of 8.0:1 which the increasing availability of higher octane fuels enabled the manufacturers to increase to 8.5:1 for the Triumph. This and the fitting of twin Stromberg 150 CD carburettors made for a claimed power output increased to 90 bhp (67 kW; 91 PS) from the Vanguard's 80 bhp (60 kW; 81 PS).

Standard transmission on the original car was a 4-speed manual gearbox. (overdrive and Borg-Warner Type 35 3-speed automatic transmission were options.) The monocoque body had independent suspension all-round using coil springs. The servo-assisted brakes were disc at the front and drums at the rear.

Triumph's 2000 competed with the contemporary Rover P6 2000, which initially was offered only with a four-cylinder engine. The Rover was also released in October 1963, just one week before the Triumph. Together the cars defined a new market sector in the UK, promising levels of comfort and luxury hitherto associated with larger Rover and Jaguar models, but with usefully lower running costs and purchase prices, all in a modern package.

Although the Mk 1 was presented to the public at the London Motor Show in October 1963, volume sales began only in January 1964. Continuing in production until 1969, this version came in saloon and, from 1965, estate forms. The estate, its body shell partly built by Carbodies, was in the Mk 1 version the same length as the saloon. Various minor improvements were made during the period of which the most noteworthy, probably, was a significant upgrade in October 1966 to the "previously rather ineffective" ventilation, with eyeball vents added in the centre of the facia and the heater controls repositioned beneath them.
