The Matra-Simca MS630 was a Group 5 prototype race car introduced in 1967 for the World Championship for Makes.

Matra planned to have Johnny Servoz-Gavin/Jean-Pierre Jaussaud to drive the MS630 at both the 1967 1000 km of Spa and 1967 1000km of Nürburgring but the entries for both races were withdrawn.

In the World Championship for Makes, Matra scored no points during the year for the second consecutive season.

Matra entered the 1000 km of Monza with Servoz-Gavin/Jean Guichet but retired from the race with a fuel feed issue.

Beltoise/Courage finished fourth followed by Guichet/Vaccarella in fifth, Galli/Widdows seventh and Servoz-Gavin/Müller retired when an electrical short circuit failed.
