The Škoda 7.5 cm Gebirgskanone M. 15 (Czech: 7,5cm horský kanón M 15; Bulgarian: 75-мм планинско оръдие "Шкода") was a mountain gun used by Austria-Hungary in World War I.

A standard Austro-Hungarian Gebirgs-Artillerie-Regimenter, which was used to beef up Field Artillery Regiments in some Corps, would be equipped with 36 Škoda M15s on paper, though in reality the number of guns and batteries varied quite a bit.

The German Army used the Škoda as a substitute for the 7.62 cm Infanteriegeschütz L/16.5 in the infantry support role with 14 Infanteriegeschütz-batallions equipped with these guns but using more powerful HE grenades than those used by the Austro-Hungarians.

While the Austro-Hungarians were generally well pleased with the Škoda, the Germans tended to use the gun in situations it wasn't designed for such as a mobile close support weapon.

The M15 was designed to be disassembled for transport but the Germans often towed them on long marches as-is, so that the main parts had a tendency to become lose or disconnected after traveling on bumpy terrain.
