The Standard Ten was a model name given to several small cars produced by the British Standard Motor Company between 1906 and 1961. The name was a reference to the car's fiscal horsepower or tax horsepower, a function of the surface area of the pistons. This system quickly became obsolete as an estimate of the power produced by the engine, but it continued to be relevant as a way to classify cars for tax purposes. Like other manufacturers, Standard continued to use the name to define the approximate size of their 'Ten' model long after the origins of the name had, in Britain, become inapplicable.

The Standard Motor Company Limited was a motor vehicle manufacturer, founded in Coventry, England, in 1903 by Reginald Walter Maudslay. For many years, it manufactured Ferguson TE20 tractors powered by its Vanguard engine. All Standard's tractor assets were sold to Massey Ferguson in 1959. Standard purchased Triumph in 1945 and in 1959 officially changed its name to Standard-Triumph International and began to put the Triumph brand name on all its products. A new subsidiary took the name The Standard Motor Company Limited and took over the manufacture of the group's products.
