The Hillman Minx was a series of middle-sized family cars produced under the Hillman marque by the Rootes Group between 1932 and 1970. There have been many versions of the Minx over the years, as well as various badge-engineered versions which were sold under the Humber, Singer, and Sunbeam marques.

For most of the 1960s the Minx and its derivatives were the greatest-volume sellers of the "Audax" family of cars from Rootes. The final version of the Minx was the "New Minx" launched in 1967, which was part of the "Arrow" family and essentially a basic version of the Hillman Hunter. Generally the Minx was available in four-door saloon and estate forms, with a 1496cc engine.

The Hillman Super Minx was a slightly larger model offered during the Audax era.

Throughout the life of the Minx there was usually an estate version, and for some time there was also a short-wheelbase estate, the Hillman Husky, and additionally a van derivative of that, known as the Commer Cob.

The Minx brand was revived briefly – along with the "Rapier" model name, as applied to the Sunbeam Rapier version of the Audax family – as a special edition late in the life of the Talbot Alpine / Talbot Solara cars, produced by Chrysler Europe after the demise of the Rootes Group.
