The Canon de 155 L Modele 1917 Schneider was a French heavy artillery piece designed and produced during the First World War.

In order to address the French Army's lack of long-range heavy artillery, Schneider placed a new barrel onto the carriage of the existing Canon de 155 mm L mle 1877/1914, which was itself based on the carriage of the 152 mm howitzer M1910 produced by Schneider for the Imperial Russian Army.

Between the wars surviving guns were fitted with solid rubber tires for horse or motor traction.

[3] In 1941, Finland bought twelve captured field guns and large amounts of ammunition from the Germans.

All twelve guns were issued to Super Heavy Artillery Battalion 1 ( Järeä Tykistöpatteristo 1) fighting in Karelian Isthmus.
