The Laffly S15 was a family of all-terrain military vehicles from French manufacturer Laffly that shared the same six-wheel drive chassis.

They were used by French forces during World War II.

When France delivered 41 Renault R-35 tanks to Romania in 1939, a number of Laffly S15T artillery tractors were also delivered.

These gun tractors were used by the 2nd Armoured Regiment's support services.
