The Triumph Herald 1200, also known as the 12-50, was a compact saloon car produced by the British manufacturer Triumph Motor Company from 1959 to 1971. It was designed by the legendary Italian coachbuilder, Michelotti, and featured a distinctive, rounded body style that was a departure from the more angular designs prevalent in the British car market. The Herald was initially available in two-door saloon and convertible body styles, with a four-door saloon version added later. It was powered by a 1.2-liter four-cylinder engine, initially producing 48 horsepower, later increased to 50 horsepower. This engine, along with the car's light weight and independent suspension, provided a surprisingly sprightly performance for its small size.

The Herald's success was built on a combination of affordability, practicality, and a touch of sporty flair. It was a popular choice for young families and for those seeking a more economical alternative to larger cars. The Herald also became a popular choice for modification and tuning, with many owners enhancing its already sporty character. It was particularly popular in motorsport, competing in a wide range of events including rallying and circuit racing. While the Herald was never intended to be a performance car, its nimble handling and light weight made it a capable competitor on the track. The introduction of the larger, more powerful Triumph Spitfire in 1962 provided a more focused sports car option from the manufacturer, but the Herald continued to be popular throughout its production run.
