The GS is a small family car manufactured and marketed by Citroën for model years 1970-1986 in sedan and wagon bodystyles (1970-1980), over a single generation. The GS received a facelift in 1979 and was subsequently marketed as the GSA in hatchback and wagon bodystyles (1979-1986).

The GS was voted European Car of the Year for 1971 and was noted as technologically advanced, with class leading comfort, safety and aerodynamics.

The GS filled the gap in Citroën's range, between the 2CV and Ami economy cars and the luxurious DS executive sedan. The DS had moved significantly upmarket from its predecessor the Citroën Traction Avant, and beyond the finances of most French motorists. Leaving this market gap open for fifteen years allowed other manufacturers entry into the most profitable, high volume market segment in France. This combined with the development costs and new factory for the DS-replacing Citroen CX, the 1974 oil crisis, and an aborted Wankel rotary engine, led Citroën to declare bankruptcy in 1974.

The GS met with instant market acceptance and was the largest selling Citroën model for many years. 1,896,742 GS models and 576,757 GSA models were produced in total.

Unlike the 2CV, DS and SM, the GS was never officially imported to the USA.

The GS took 14 years to develop from initial design to launch.

In 1956, Citroën developed a bubble car prototype to fill the gap in its range between the DS and the 2CV, known as the C10. Development continued with ideas like a Wankel engine and hydropneumatic suspension suggested as possibilities, with a new, modern body to match. Another iteration was the "C60," which resembled an Ami 6 with a long, smooth nose.
