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 the first model in a new line of Triumph vehicles designed by Italian coachbuilder Michelotti, known for their sleek and elegant styling. The Herald was a radical departure from the previous Triumph models, featuring a unitary construction body, front-wheel drive, and a transverse engine – a configuration considered quite innovative for the time. The car was powered by a 1.2-liter four-cylinder engine, producing 48 horsepower. Despite its small size, the Herald offered comfortable seating for four passengers and a surprising amount of cargo space. Its compact dimensions, maneuverability, and fuel efficiency made it popular in urban environments, while its stylish aesthetics and affordable price made it appealing to a wide range of buyers.

The Herald was offered in a variety of body styles throughout its production run. The standard saloon was joined by the drophead coupé, the estate (known as the "Estate 1200"), and the sporty convertible "Spitfire" – a car that, while sharing its platform with the Herald, was later spun off into its own series. The 12-50 was also instrumental in launching the careers of several notable figures in the automotive industry. Both the designer Michelotti and the engineer Harry Webster, who brought the Herald to life, later went on to achieve great success in their respective fields. As a result, the Herald is also remembered as a significant contributor to the evolution of automotive design and engineering in the post-war era.
