The Matra MS620 (sometimes referred to as the M620) was a Group 6 sports prototype built by Matra in 1966, and was the second such car built by the company. Fitted with a 1.9 litre version of the BRM Formula One V8 engine, four cars were built, but were mostly used as developmental cars. In 1967, the MS620 was replaced by the 3 litre Matra MS630, although it was used in the Le Mans Test of that year, fitted with a 4.7 litre Ford V8 engine.
