The Simca 5 is a small Franco-Italian passenger car designed by Fiat engineers at Turin. It was produced and sold in France by Simca. It was virtually identical to the Fiat 500 Topolino on which it was based, but was first presented, at the company's new Nanterre plant, three months ahead of the Fiat equivalent on 10 March 1936. Production was delayed, however, by a wave of strikes that accompanied the June 1936 electoral victory of Léon Blum's Popular Front government.

Advanced features boasted by the Simca 5 included independent front suspension, a four speed gear box, hydraulically controlled drum brakes on all four wheels and a twelve volt electrical system.

The car also offered exceptional fuel economy: in a test it managed to travel 110 kilometers on just 5 litres of fuel.

The car was intended for sale on the domestic market for less than 10,000 French Francs, an aspiration that would be overtaken by a decline in the currency's value that gathered pace in the second half of the 1930s. The manufacturer boasted at the time of its launch of being ahead of the plans across the Rhine: this was a reference to the already rumoured launch of the Volkswagen Beetle which would appear only in 1938.

Production of the Simca 5 was slowed down (but did not ever cease entirely) by the war and the period of German occupation in the early 1940s, but resumed in 1946. 46,472 of the cars had been produced by the time the car was delisted by Simca in 1949. By now it had been replaced on the company's production lines by the similar but partially reskinned and slightly more powerful Simca 6.
