The Canon de 155 L modèle 1918 Schneider was a French heavy artillery piece designed and produced during the First World War.

At the beginning of World War I, the French Army had about 1,300 de Bange 155 mm L modèle 1877 guns in its inventory.

In order to address a lack of heavy artillery, Schneider produced the Canon de 155 L modèle 1877/14 which mated the barrel of the mle 1877 with the box-trail carriage and hydro-pneumatic recoil mechanism of the 152 mm howitzer M1910 produced by Schneider for the Imperial Russian Army.

The result was the Canon de 155 L modèle 1917, a heavy gun which lacked mobility but had good range.
