The Voisin C26 was a large passenger car built in 1934.

At the 1934 Motor Show, a new model appeared on the C25 chassis. This was the C26, which was to be available the two body styles. These body styles were a four-door saloon called the Aérisée and a four-door limousine called the Chevalièr.

It seems certain that at least one example of this model used the C25 engine (the Aérisée), the but it unknown which engine the Chevaliere limousine was fitted with.

It is also not know how may C26s were produced.
