The OSI-Ford 20 M TS is a coupe produced by the Italian car manufacturer Officine Stampaggi Industriali (abbreviated OSI).

The vehicle was technically based on the Ford 20M and was manufactured between 1967 and 1968.

A unique OSI Ford convertible was shown at the 1967 Paris Salon.

Since 1987, the OSI Owners Association in Germany with reproductions and annual meetings cares about the legacy of OSI.

Sources vary on the total number of cars made: some suggest 2,200,[1] others 3,500,[2] while only around 200 examples are known to exist today.
