The Triumph TR6 (1969–76) was a British sports car and the best-seller of the TR range built by Triumph when production ended in July 1976. This record was then suppased by the TR7. 91,850 TR6s were built.

All TR6 sports cars featured inline six-cylinder engines. For the US market the engine was carbureted, as had been the US-only TR250 model's engine. For other world markets including England, the TR6 was fuel-injected as had been the non-US market TR5. The Lucas mechanical fuel injection system helped the home-market TR6 produce 150bhp at model introduction. As air pollution standards came into effect both TR6 variants were detuned for compliance, and they produced less horsepower.

The TR6 featured a four speed manual transmission. An optional equipment overdrive unit was a desireable feature because it gave drivers close-gearing for aggressive driving, yet "long legs" for open motorways. TR6 also featured independent rear suspension, fifteen inch wheels and tires, pile carpet on floors and boot, bucket seats, and a full complement of instrumentation. Braking was accomplished by disc brakes in the front; drum brakes in the rear. A factory steel hard top was optional. TR6 construction was fundamentally old-fashioned: the body was bolted onto a frame instead of the two being integrated into a unibody structure; the TR6 dashboard was wooden.

Besides the TR250 and TR5, the TR6 was also preceded by a series of four-cylinder Triumph TRs: TR2, TR3, TR3A, TR4, and TR4A. TR6 was succeeded by the four-cylinder TR7 and the eight-cylinder TR8.

The Triumph TR6 is supported by active clubs and reliable service parts suppliers. There is also an active community of performance tuners. Because it has a relatively large engine compartment, the TR6 is a popular car for converting to a more powerful V8 engine.
